Lips Without Living: Beware the Danger of Mental Assent

Devotional

Day 1: The Son Who Changed His Mind

The father stood in the field, dust clinging to his sandals, and told his son, “Go work today.” The son crossed his arms. “I will not.” But later, regret twisted his gut. He wiped sweat from his brow as he hoed the vineyard’s stubborn soil. His “no” became “yes” through repentance. Obedience bloomed in action, not just intention. [35:31]

Jesus honored the son’s turnaround. God values hearts that pivot from rebellion to surrender. The Father’s call—whether to serve, forgive, or repent—demands more than polite nods. It requires dirt-under-the-nails obedience.

How often do you delay repentance, assuming tomorrow holds space for change? The vineyard waits. What “I will not” in your life needs to become “I will go” today?

“But what think ye? A certain man had two sons; and he came to the first, and said, Son, go work to day in my vineyard. He answered and said, I will not: but afterward he repented, and went.”
(Matthew 21:28-29, KJV)

Prayer: Ask God to reveal one area where your “no” needs to become a repentant “yes.”
Challenge: Write down one delayed obedience. Do it before sunset.

Day 2: Lips Without Living

The second son smiled, bowed, and said, “I go, sir.” His words hung like ripe grapes—sweet but uneaten. He never touched the vineyard’s soil. Respectful language masked a stagnant heart. Jesus rebuked such hollow agreement: “Faith without works is dead.” [31:30]

God sees past polished responses. He examines hands, not just hymns; service, not just sermons. The Pharisees knew Scripture but starved their souls with unacted truth.

You might say “Amen” to forgiveness yet nurse a grudge. You might praise generosity but clutch your wallet. Where do your words outpace your deeds?

“And he came to the second, and said likewise. And he answered and said, I go, sir: and went not.”
(Matthew 21:30, KJV)

Prayer: Confess one instance where your lips lied to God. Beg for grace to align speech with action.
Challenge: Text someone you’ve wronged or avoided. Set a time to make it right.

Day 3: Mercy’s Fresh Batch Today

The preacher shouted, “I got a fresh batch of mercy today!” The crowd roared. Mercy isn’t a relic—it’s daily bread. Like manna in the wilderness, God’s compassion renews at dawn. You don’t live on yesterday’s mercy. You knead today’s portion into your bones. [27:03]

Jesus modeled this rhythm. He withdrew daily to pray, gathering new strength for healing and truth-telling. The Father’s mercies aren’t rationed. They overflow for the humble.

What old failure are you reheating? What shame needs replacing with today’s mercy?

“It is of the Lord’s mercies that we are not consumed, because his compassions fail not. They are new every morning: great is thy faithfulness.”
(Lamentations 3:22-23, KJV)

Prayer: Thank God for three specific mercies He gave you this week.
Challenge: Throw away one item symbolizing past guilt (a note, photo, etc.).

Day 4: From Harlots to Kingdom Gates

Jesus shocked the temple leaders: “Harlots enter God’s kingdom before you.” These women clutched grace with both hands, their repentance raw and urgent. They didn’t hide behind theological debates. They ran to the Father, robes stained but hearts clean. [30:33]

God prioritizes messy surrender over polished hypocrisy. The kingdom belongs to the hungry, not the self-sufficient. Tax collectors wept while priests preened.

What keeps you from raw repentance? Respectability? Fear of exposure?

“Verily I say unto you, That the publicans and the harlots go into the kingdom of God before you.”
(Matthew 21:31, KJV)

Prayer: Ask God to break your pride with holy desperation.
Challenge: Donate clothes or funds to a ministry serving marginalized people.

Day 5: Today in the Vineyard

The father’s command pulsed with urgency: “Go work TODAY.” Not tomorrow. Not after excuses. The vineyard’s grapes wouldn’t wait. Jesus’ parable echoes Moses’ warning: “TODAY, if you hear His voice.” Delay is disobedience dressed in procrastination’s robes. [35:07]

God’s “today” demands response. The Spirit nudges you to apologize, serve, or repent—not next week. Hell’s lies whisper, “You have time.” Heaven shouts, “Now is the day.”

What divine “today” have you downgraded to “someday”?

“But exhort one another daily, while it is called To day; lest any of you be hardened through the deceitfulness of sin.”
(Hebrews 3:13, KJV)

Prayer: Beg God for courage to obey His loudest “today” prompt.
Challenge: Set a phone reminder labeled “Vineyard Now.” Act when it rings.

Sermon Summary

Jesus sets Matthew 21:28-32 in front of the house like a mirror. The Father says, go work today in my vineyard. The first son answers, I will not, but afterwards he repents and goes. The second son answers, I go, sir, but he goes nowhere. Jesus declares that the tax collectors and the prostitutes go into the kingdom before the religious because they believed John and repented while the religious only agreed and stayed still. The text names the danger: mental assent, lips with no living. Respectful language, proper theology, and church posture cannot replace surrender. God does not look at the outward; God reads the heart.

The first son runs a holy arc: rebellion to repentance to obedience. The second son runs a tragic arc: respect to agreement to disobedience. Faith without works is dead, and love is an action word. Today matters. Delayed obedience is disobedience. Saying yes, Lord without movement is still no. The call is not just to acknowledge that there is a God, but to bow, to go, to do, to finish in Him.

God’s works stretch from creation to providence to redemption to sanctification. He made all things seen and unseen. He governs what He made with care. He redeemed by the blood of Jesus, the only perfect man who laid His life down and took it up again. He sanctifies by the Holy Spirit, who woos, teaches, corrects, brings back to remembrance, and assigns kingdom work in ordinary places. The work for the believer on the ground is what Jesus says it is: believe in the One the Father has sent, and then act like it. New creatures speak life, exercise authority, intercede, and obey quick when the Spirit nudges, even if the assignment looks like a quiet “drive by” prayer on aisle 6.

The kingdom refuses comparison and competition and chooses celebration. Knowledge is for application and sharing, not for swollen heads. Respectability cannot replace repentance. When truth shows up, repentance should be quick and concrete, a 180. The Father still chastises sons and daughters He loves, not to shame but to yield fruit. Jesus has prayed that faith would not fail, so the church is called to believe in the middle of trouble and keep moving. God welcomes the repentant with arms wide open. The invitation stays live: no more lips without living.

Key Takeaways

1. Repentance outruns respectful lip service Repentance is not a vibe, it is a turn. The first son shows that a bad start can become a faithful finish when the heart bows and the feet move. Respectful words without movement still land as no. The kingdom opens to those who repent when confronted by truth. [41:39]
2. Believing Jesus is the Father’s work The core assignment is not impressing God with effort but trusting His Son and then acting on that trust. Belief is not brain-only; it spills into obedience, intercession, and mercy. Faith ties into the cross, the blood, and the Spirit’s sanctifying push. Jesus names believing as the work God wants. [50:17]
3. Delayed obedience counts as disobedience “Today” is the Father’s timeline for the vineyard. Postponed yeses become practical noes, and spiritual drift hides inside polite intentions. God’s grace welcomes repentance, but His call carries urgency that should reset calendars and ankles. Finish in Him by moving when He speaks. [62:32]
4. The Spirit assigns, believers act today Providence is not passive; the Spirit gives real-time assignments in ordinary places. New creatures carry authority to pray, speak life, and love on purpose, even between errands. Obedience to small nudges trains the heart for bigger yeses. Kingdom work often looks like showing up when He whispers. [51:22]

Bible Reading
Matthew 21:28-32 (ESV)
“What do you think? A man had two sons. And he went to the first and said, ‘Son, go and work in the vineyard today.’ And he answered, ‘I will not,’ but afterward he changed his mind and went. And he went to the other son and said the same. And he answered, ‘I go, sir,’ but did not go. Which of the two did the will of his father?” They said, “The first.” Jesus said to them, “Truly, I say to you, the tax collectors and the prostitutes go into the kingdom of God before you. For John came to you in the way of righteousness, and you did not believe him, but the tax collectors and the prostitutes believed him. And even when you saw it, you did not afterward change your minds and believe him.”

Observation Questions

In the parable, how do the two sons’ actions differ from their initial responses to their father’s request?
What specific groups does Jesus say will enter God’s kingdom before the religious leaders, and why?
According to the parable, what does Jesus equate with true obedience: words or actions?

Interpretation Questions

Why might Jesus use tax collectors and prostitutes as examples of those who “believed” and repented, while the religious leaders did not? What does this reveal about God’s priorities?
The sermon states, “Delayed obedience is disobedience” [01:02:32]. How does the parable of the two sons illustrate this principle?
What does it mean that “faith without works is dead” (James 2:26) in the context of the second son’s response?

Application Questions

Reflect on a time you said “yes” to God (e.g., in prayer, commitments, or intentions) but delayed or avoided follow-through. What practical step could you take today to align your actions with your words? [01:02:32]
The sermon warns against “mental assent” (agreeing with truth but not acting on it) [41:39]. Where in your life do you find yourself nodding to God’s commands without surrendering your choices or habits?
The Holy Spirit often gives “real-time assignments in ordinary places” [51:22]. What small, immediate act of obedience (e.g., a prayer, encouragement, or act of mercy) have you felt prompted to do recently? How will you act on it this week?
Repentance is described as a “180-degree turn,” not just regret. Is there an area where you need to make a concrete change in direction rather than just feeling sorry? What would that look like practically?
The parable contrasts “respectful language” with a surrendered heart. How can you guard against using spiritual routines (like church attendance or Bible study) as substitutes for genuine surrender to God?
The sermon emphasizes urgency: “Today matters” [30:00]. What is one area of your life where you’ve been postponing obedience, and how will you prioritize it this week?

#FaithNeedsAction

“Mental ascent is simply this, it is when someone agrees with truth intellectually that never acts on it. It is the second son in this particular parable. He says, I go sir but yet he did not go. Somebody say, faith without works is dead. James chapter two verse 26, faith without works is dead. But what is the work of God? I wanna give you a long definition. Here go that that Siri helped me with.”
