God's Justice, Mercy, and Our Identity in Christ

Devotional

Day 1: God’s Care and Dignity for the Outsider

God’s law commands compassion and dignity even for those who begin as outsiders, welcoming them into the community and ensuring they are treated with respect and honor. In Deuteronomy 21:10-14, the foreign woman taken captive is not to be treated as a slave but is given time to mourn, is welcomed as a wife, and, if released, is granted her freedom and dignity. This reflects God’s heart for the vulnerable and foreshadows the way He welcomes all who were once far off into His family through Christ. Consider how God’s compassion for the outsider is a model for how we are to treat others, especially those who are new, different, or vulnerable in our midst. [01:07:04]

Deuteronomy 21:10-14 (ESV)
“When you go out to war against your enemies, and the Lord your God gives them into your hand and you take them captive, and you see among the captives a beautiful woman, and you desire to take her to be your wife, and you bring her home to your house, she shall shave her head and pare her nails. And she shall take off the clothes in which she was captured and shall remain in your house and lament her father and her mother a full month. After that you may go in to her and be her husband, and she shall be your wife. But if you no longer delight in her, you shall let her go where she wants. But you shall not sell her for money, nor shall you treat her as a slave, since you have humiliated her.”

Reflection: Who in your life or community might feel like an outsider, and what is one tangible way you can extend dignity and welcome to them this week?

Day 2: Honoring the Unloved and Upholding Justice

God’s law insists on justice and honor for those who might otherwise be overlooked or mistreated, such as the unloved wife and her firstborn son, ensuring that inheritance and dignity are not denied because of favoritism. The rights of the firstborn are protected, regardless of the father’s affections, reminding us that God’s justice is not swayed by human partiality. This principle calls us to honor and care for those who may be marginalized or less favored, recognizing their worth and the importance of upholding what is right, even when it is inconvenient or counter to our preferences. [01:08:59]

Deuteronomy 21:15-17 (ESV)
“If a man has two wives, the one loved and the other unloved, and both the loved and the unloved have borne him children, and if the firstborn son belongs to the unloved, then on the day when he assigns his possessions as an inheritance to his sons, he may not treat the son of the loved as the firstborn in preference to the son of the unloved, who is the firstborn, but he shall acknowledge the firstborn, the son of the unloved, by giving him a double portion of all that he has, for he is the firstfruits of his strength. The right of the firstborn is his.”

Reflection: Is there someone in your family, workplace, or church who is often overlooked or undervalued? How can you intentionally honor or advocate for them this week?

Day 3: The Seriousness of Rebellion and the Call to Discipline

Persistent, stubborn rebellion is not merely a family issue but a spiritual one, reflecting a heart that resists both human and divine authority; loving discipline is necessary to guide and protect, even when it is difficult. The passage about the rebellious son shows that unchecked defiance can be destructive to both individuals and the community, and that true love sometimes requires hard boundaries and correction. God’s commands here remind us that discipline, when done with justice and care, is an act of love that seeks restoration and life, not harm. [01:13:56]

Deuteronomy 21:18-21 (ESV)
“If a man has a stubborn and rebellious son who will not obey the voice of his father or the voice of his mother, and, though they discipline him, will not listen to them, then his father and his mother shall take hold of him and bring him out to the elders of his city at the gate of the place where he lives, and they shall say to the elders of his city, ‘This our son is stubborn and rebellious; he will not obey our voice; he is a glutton and a drunkard.’ Then all the men of the city shall stone him to death with stones. So you shall purge the evil from your midst, and all Israel shall hear, and fear.”

Reflection: Is there an area in your life where you are resisting godly correction or discipline? What step can you take today to humbly receive guidance and turn back to the Lord?

Day 4: God’s Law Reveals His Love and Mercy

Even in the most challenging and specific Old Testament laws, God’s love, mercy, and care for His people shine through; His commands are not arbitrary but are given for our good, to shape a just and compassionate community. The laws in Deuteronomy 21, though ancient and sometimes difficult to understand, reveal a God who cares deeply for the vulnerable, the marginalized, and even the rebellious, always providing a way for restoration and dignity. In Christ, we see the ultimate fulfillment of this love, as He welcomes us—outsiders, the unloved, and the rebellious—into His family and gives us a new identity and inheritance. [01:21:30]

Psalm 105:1-5 (ESV)
“Oh give thanks to the Lord; call upon his name; make known his deeds among the peoples! Sing to him, sing praises to him; tell of all his wondrous works! Glory in his holy name; let the hearts of those who seek the Lord rejoice! Seek the Lord and his strength; seek his presence continually! Remember the wondrous works that he has done, his miracles, and the judgments he uttered.”

Reflection: How does seeing God’s mercy and care in His commands change the way you view His law and your obedience? What is one way you can express gratitude for His love today?

Day 5: Our New Identity and Inheritance in Christ

Through Christ, we who were once outsiders, unloved, or rebellious are now welcomed as beloved children, given a priceless inheritance, and assured of God’s unending care; our identity is secure in Him. The gospel transforms the shadows of Deuteronomy into glorious realities: we are the bride brought in, the firstborn given honor, the rebellious son redeemed by the true Firstborn’s sacrifice. Rest in the assurance that you are precious to God, united to Christ, and called to live out this new identity with joy, gratitude, and hope. [01:27:14]

2 Corinthians 5:17 (ESV)
“Therefore, if anyone is in Christ, he is a new creation. The old has passed away; behold, the new has come.”

Reflection: What old identity or label do you need to let go of today in order to fully embrace your new identity as God’s beloved child in Christ?

Sermon Summary

This morning, we gathered in gratitude and awe before our holy and merciful God, recognizing the privilege of worshiping together as his people. We began by acknowledging the Lord’s faithfulness, his new mercies each morning, and the immeasurable gift of salvation in Christ. As we confessed our sins—both those we remember and those we forget—we were reminded not to be trapped by guilt, but to trust in the forgiveness that is ours by grace through faith. The assurance that “if anyone is in Christ, he is a new creation” brought comfort and joy, leading us to sing of the deep love of the Father.

Turning to Deuteronomy 21:10–21, we explored three seemingly peculiar laws about family life in ancient Israel: the treatment of a captive woman taken as a wife, the rights of the firstborn son of an unloved wife, and the case of a persistently rebellious son. While these laws may appear distant or harsh, they reveal God’s deep concern for justice, dignity, and the well-being of his people. The captive woman is to be treated with compassion and dignity, not as a slave. The firstborn son’s rights are to be honored, regardless of his mother’s status, ensuring justice and care for the vulnerable. Even in the case of the rebellious son, the process is marked by repeated parental discipline and the requirement of communal judgment, underscoring the seriousness of sin and the need for order and respect within the covenant community.

These laws are not arbitrary restrictions but expressions of God’s wisdom and love, designed for the good of his people and the health of society. They point us to the greater realities fulfilled in Christ. Like the foreign woman, we were once outsiders, but Christ has brought us into his family and will never cast us out. Like the firstborn son, we have received an unshakeable inheritance in Christ. And though we were once rebellious, Christ, the true and faithful Son, took our place, bearing the penalty we deserved so that we might be forgiven and welcomed as God’s beloved children.

As we celebrated the Lord’s Supper, we remembered that we are gathered as a family around Christ, our elder brother, receiving the benefits of his sacrifice and looking forward to the marriage supper of the Lamb. We are called to cherish these truths, to rest in God’s love, and to live as grateful, joyful servants, ready to share the hope of the gospel with others.

Key Takeaways

1. God’s laws, even those that seem obscure or difficult, are rooted in his care for justice, dignity, and the flourishing of his people. The treatment of the captive woman and the unloved wife’s son demonstrates that God’s heart is for the vulnerable and marginalized, calling us to reflect his compassion in our own relationships and communities. [78:08]
2. The seriousness of persistent rebellion in the family is not merely about parental authority, but about the health of the entire covenant community and, ultimately, one’s relationship with God. True love does not coddle or excuse destructive behavior, but seeks repentance and restoration, even when it is costly or difficult. [73:56]
3. The inheritance of the firstborn son, protected by God’s law, points us to the greater inheritance we receive in Christ. Our status as God’s children is not based on our merit or the world’s standards of worth, but on God’s gracious choice and the work of Christ, who secures for us an eternal inheritance that cannot be lost. [82:33]
4. The gospel is foreshadowed in these laws: we were once outsiders, unloved, and rebellious, but Christ has brought us in, given us dignity, and borne the penalty for our sin. The mercy and grace shown to the foreign woman and the rebellious son are but shadows of the greater mercy we have received in Jesus, who took our place and made us part of God’s family. [83:53]
5. God’s discipline and commands are not meant to burden us, but to lead us into life, peace, and joy. In Christ, we are not only forgiven but made new, precious in God’s sight, and empowered by the Spirit to live as his sons and daughters. Our response is to rest in his love, cherish our place in his family, and extend that same grace to others. [87:14]

So you shall purge the evil from your midst, and all Israel shall hear, and fear.”

Sermon Clips

Because how a child, how a son, learns to respect parents is a reflection and a key element of how they will have a right attitude, not just to their parents, but to broader Israelite society and to indeed God himself. God has told that son, honor your father and your mother. His failure to do so, his stubborn, repeated failure to do so is again, defiance of God himself. This goes beyond mom and dad. It's defiance of God himself. [01:14:43] (39 seconds) #RespectReflectsFaith

Paul writes to Timothy and tells him quite clearly all scripture, including Deuteronomy, is inspired by God. It's given by God to us and is profitable for us. Doctrine, reproof, correction, instruction in righteousness for a purpose that we might be complete and equipped for every good work that God has called us to do. [01:17:03] (27 seconds) #ScriptureEquipsBelievers

God shows his compassion, his care, his love for his people by giving them these laws that are good for them, good for their lives, good for the ordering of a healthy society. So when we consider God's law in the Old Testament here in Deuteronomy, it's not just a collection of a bunch of restrictions meant to make life hard and inconvenient. Let's not turn God into a legalist. He's not a stern judge up on high pronouncing rules based on his petty whims. God's laws are good. They're meant for the good of his people. They are holy. They are just. They are right. And in them, he shows his love and mercy and grace. [01:21:01] (48 seconds) #LawsReflectGodsLove

And this comes to bear for us because if we're honest with ourselves, God has shown that same kind of love and mercy and grace to us in and through Christ Jesus, our Savior. In some sense, are we not like the foreign woman? In our sin, without Christ, we are. We're outside the people of God. We were outside the people of God. And here, Christ, as our husband, has taken us to himself, made us part of his glorious bride, the church, and he will never cast us out. [01:21:51] (41 seconds) #GraceInChristOurBridegroom

And also, in some sense, are we not similar to the son of the unloved woman? One can argue, I think, validly so, that in all of humanity, throughout all of history, there are only two kinds of people in the world, the righteous and the unrighteous. Seed of the woman, the seed of the serpent. You're a son of one or the other, figuratively, metaphorically speaking. And those with only the inheritance of the serpent have a perishable passing inheritance. But those who are sons of Abraham, by grace, through faith, believing and trusting in the promises of God, receive an internal inheritance, Ephesians 1, that cannot be shaken, kept, guarded in heaven for us, says Peter to the church, 1 Peter 1, verse 4. That's a gift. That inheritance is a gift that cannot be earned, it can't be bought, it's received by faith and by faith alone in Jesus as Savior. [01:22:45] (79 seconds) #FaithSecuresEternalInheritance

And perhaps even more than those two, are we not without Christ, without Christ we are lost, without Christ in our sins, are we not very much like the rebellious son, rebels against God, defiantly shaking our fist at him with our sin, and the wages of that sin is death. We merit death in our sin. You think the punishment of the son is harsh? Do not forget the punishment for sin, death, eternally. That means forever. And this is just and right before the holy, holy, holy Lord God. [01:24:05] (46 seconds) #SinDeservesDeath

``Yet, yet, but God, the two well-loved words in our Bible. God has made a glorious provision of salvation for lost, rebellious sinners in his firstborn, only begotten son, ever faithful, who willingly took the place of us rebellious brothers and sisters, took the penalty of death that we deserve, paid it in full, complete, done, accomplished, once for all time, rose from death to life as our Father in Heaven accepted his work, his wrath appeased the just penalty having been paid. [01:24:51] (55 seconds) #GodsProvisionInChrist

And now, in repentance of sin and faith in Christ Jesus as Savior, all are invited to come. Admit your sin. Be honest. Seek the forgiveness that God freely offers. Receive it by faith. You can't buy it. You can't work for it. And then rest. Rest on the work that Jesus has done. You can't add to it. Rest. [01:25:48] (29 seconds) #FaithRestInJesus

For all of you who have already come, my friends, friends, never forget that our God and Father cares for you. You are precious in his sight. Like, even more so than that foreign captive wife. Even more so than the firstborn son of the unloved woman. United in faith to his very own son, Christ Jesus, part of his body, the bride of Christ. Are we not more precious to God than they are? His spirit poured out upon us. Are we not more powerfully united to him, more closely to him than they were in this external covenant? We have the covenant written on our hearts, not on stone. You are his son. You are God's daughter. You have a precious and a priceless inheritance. And your father cares for you. And he always will. [01:26:17] (84 seconds) #PreciousInGodsEyes
