Fully Alive in Christ: A New Self – Putting Sin to Death

Devotional

Day 1: The Mold in the Shower – Daily Battle Against Sin’s Residue

Sin’s lingering presence demands daily attention, like stubborn mold growing in humid corners. Left unchecked, it spreads quietly, corrupting what was meant to be clean. The Christian life requires intentional, repetitive action to scrub away what remains of our old nature. This isn’t about perfection but persistence, relying on the Spirit’s power to expose and cleanse hidden residues. Victory comes through recognizing our new identity in Christ, not mere willpower. Each day offers fresh mercies to confront what seeks to take root. [07:01]

“Put to death therefore what is earthly in you: sexual immorality, impurity, passion, evil desire, and covetousness, which is idolatry. On account of these the wrath of God is coming.” (Colossians 3:5–6, ESV)

Reflection: What specific “residue” of sin tends to regrow in your heart when left unchecked? How might your daily habits shift to actively scrub it away with Christ’s strength?

Day 2: Thirsty for Seawater – The Deception of Sin’s False Promises

Sin parches the soul while masquerading as satisfaction. Like drinking seawater, it intensifies cravings even as it poisons. The world sells greed, lust, and pride as pathways to fulfillment, but they only deepen emptiness. Jesus alone quenches the thirst our idols cannot. Every sinful desire whispers lies about God’s goodness and sufficiency. To kill sin is to starve its deceit by feasting on Christ’s living water. [10:30]

“But each person is tempted when he is lured and enticed by his own desire. Then desire when it has conceived gives birth to sin, and sin when it is fully grown brings forth death.” (James 1:14–15, ESV)

Reflection: Where have you believed sin’s lie that it can satisfy more than Jesus? What tangible step will you take today to drink deeply from His truth instead?

Day 3: Dirty Clothes or New Identity? Choosing What Fits Christ

No one cleans up only to rewear filth. Yet believers often slip back into old patterns, forgetting their stained past is discarded. In Christ, we’ve been given a new wardrobe of righteousness—a identity that fits our redeemed purpose. Clinging to sinful habits dishonors the One who clothed us in grace. Every choice to “put off” the old self is a declaration of who we truly are. [25:58]

“Do not lie to one another, seeing that you have put off the old self with its practices and have put on the new self, which is being renewed in knowledge after the image of its creator.” (Colossians 3:9–10, ESV)

Reflection: What “dirty clothes” do you still reach for out of habit? How might remembering your new identity loosen their grip on your choices?

Day 4: The Monster’s Tongue – Drastic Acts for Radical Obedience

Some sins demand violent rejection, like severing a monster’s deadly tongue. Passivity guarantees defeat. Anger, slander, and malice cannot be managed—they must be executed. This isn’t a polite self-improvement plan but a war against soul-killing foes. Victory requires specific, ruthless action: blocking toxic inputs, confessing hidden hatreds, or severing compromising relationships. Mercy comes through murdering what seeks to destroy. [36:24]

“Let not sin therefore reign in your mortal body, to make you obey its passions. Do not present your members to sin as instruments for unrighteousness, but present yourselves to God as those who have been brought from death to life.” (Romans 6:12–13, ESV)

Reflection: What specific “head” needs cutting off in your life? What radical step will you take this week to starve its influence?

Day 5: Knowing Christ’s Heartbeat – Relational Knowledge That Transforms

True renewal comes not from memorizing facts but marinating in Christ’s presence. Like learning a spouse’s quirks through shared life, we grow by walking with Jesus in ordinary moments. This knowledge reshapes desires, making sin’s hollow promises easier to resist. Every choice to pray, serve, or meditate on Scripture tunes our hearts to His rhythms. Closeness with Him is both the means and the end of holiness. [30:36]

“And have put on the new self, which is being renewed in knowledge after the image of its creator.” (Colossians 3:10, ESV)

Reflection: What practical habit could deepen your relational knowledge of Christ this month? How might this intimacy weaken sin’s appeal in your weakest areas?

Sermon Summary

Paul roots the charge in identity. God has rescued from darkness, raised with Christ, and hidden life with Christ in God. When Christ who is life appears, his people will appear with him in glory. Therefore the text says, put to death what is earthly. The knife is aimed at sexual immorality, impurity, passion, evil desire, and greed which is idolatry. Greed here is the desire for more, especially more sexual sin, but in truth anything loved more than God. Sin is like drinking seawater, promising to quench but killing with every gulp, or like the child who is bored ten minutes after a new toy and wants bigger. Desire always reaches for more.

Jesus says the heart is the issue. Sinful actions begin with sinful desires, so sinful desires are sin. The question moves from behavior to affection: what does a person want most, and why. Because of such things the wrath of God is coming on the sons of disobedience. That used to be the old walk. But now the text calls for putting off practices that rot community and profane God’s name: anger, wrath, malice, slander, obscene talk, and lying. Words are not throwaway. God is not an exclamation point. Lying is not a white lie; it is a lie told to the face of God.

The command then turns positive. The new self has been put on, and it is being renewed in true knowledge according to the image of its Creator. Salvation is more than a fire escape. God is restoring his image distorted in Adam. In Adam there is death; in Christ there is life. Sanctification has a position and a progress. God declares righteous and keeps remaking into the likeness of Jesus. Knowledge fuels this renewal, not as trivia but as relational knowing that exposes error and empowers obedience. In Christ there is no ethnic, ritual, or class barrier. Against the old lie that matter is bad and spirit is safe, the body matters to God, and truth is open to all.

So killing sin must be practical. Perspective shifts to things above. Love learns to want God more than sin. Choice happens in the moment, especially between first look and second. Failure meets repentance and cleansing. The call is not passivity but a decisive, even drastic act. Off with its head.

Key Takeaways

1. Kill sin from your new life Killing sin is not self-salvation but the outworking of union with Christ. Identity precedes activity, and grace empowers the command. The residue must be scrubbed daily, like mold that spreads if ignored. The Spirit enables real, repeated no’s to old desires. [06:21]
2. Expose greed as heart idolatry Greed is not only about money but the restless desire for more of whatever is loved above God. That craving runs on lies, like seawater that dehydrates while promising relief. Naming the idol clarifies the battle, because worship always directs habits. The cure is a greater love, not a stronger will. [09:49]
3. Put off words that deface truth Anger, slander, obscene talk, and lies are not minor leaks; they flood the heart’s contents into the open. Words either honor God’s holiness or vandalize his image in others. To treat God’s name as filler is to forget his weight; to lie is to act as if he is not in the room. Reverent speech is discipleship in miniature. [21:16]
4. Put on the new self daily The Christian does not bathe then climb back into filthy clothes. God has already clothed his people with a new self; now daily choices align with that gift. Renewal comes through true knowledge of the Creator, restoring the image distorted in Adam. Position anchors progress, and progress confirms position. [26:13]
5. Fight by perspective, love, and choice Set the mind on things above, seek to love God more than the sin that courts the heart, and make the next obedient choice. The first look may be unplanned; the second look is a decision. When failure comes, honest confession keeps the heart soft and the path open. Grace trains, cleanses, and keeps. [33:45]

Bible Reading
Colossians 3:5-11 (ESV)
5 Put to death therefore what is earthly in you: sexual immorality, impurity, passion, evil desire, and covetousness, which is idolatry. 6 On account of these the wrath of God is coming. 7 In these you too once walked, when you were living in them. 8 But now you must put them all away: anger, wrath, malice, slander, and obscene talk from your mouth. 9 Do not lie to one another, seeing that you have put off the old self with its practices 10 and have put on the new self, which is being renewed in knowledge after the image of its creator. 11 Here there is not Greek and Jew, circumcised and uncircumcised, barbarian, Scythian, slave, free; but Christ is all, and in all.

Observation questions

The sermon emphasizes that “the second look is a decision” ([34:34]). What temptation do you need to actively turn away from before it escalates?
Colossians 3:11 says Christ unites all believers. Is there a relationship or group you struggle to see through this lens? How could you pursue reconciliation or humility?

We have a new life in Christ.”

#NoWhiteLies

“"There's no such thing as a small lie or a white lie. All lies are told in the face of God and to the face of God because we live before him every day of our lives. Michael, did you clean your room? Yeah. But it's still a mess. Michael, did you do your homework? Yeah. Oh, I better do it now. God takes lies very seriously, and we should too.”

#OnlyJesusSaves

“"Maybe you think, I would love to have victory over my sin. But you realize you're still enslaved to sin and to darkness. Only Jesus can free you. He is God. He died on the cross for your sins and for your shame. He physically resurrected three days later. And today, by God's grace through faith in him alone, he will adopt you and forgive you and bring you into his forever family when you trust in him by faith. Turn away from your sin and trust in him alone for salvation.”

#ResistTheSecondLook

“"When a sinful thought comes into our minds or when temptation is present, we have a choice to make. Will we continue to think about that sinful thought, or will we reject it? Will we give into temptation or not? Now, we may not be able to avoid that first look, but you know what? That second look is our choice. One step of obedience draws us closer to Christ. And last, failure. Sometimes we fail. Sometimes we give into sin. What do we do? Repent.”
