Impossible with Man, Possible with God
Discovering the Miraculous Power of God in Our Deepest Human Impossibilities
Sermon Summary
This sermon addresses the central issue of human self-reliance and spiritual helplessness. Through the teachings and encounters in Luke 18, Jesus demonstrates that salvation and kingdom living are humanly impossible through moral striving, wealth, or religious performance. The biblical truth taught is that God sovereignly accomplishes what humanity cannot achieve, providing justification and redemption through grace. Believers are called to abandon spiritual pride, cry out for divine mercy, and yield total allegiance to Jesus Christ.
Introduction
Every human heart eventually confronts the wall of impossibility. We encounter circumstances in our families, personal struggles, and moral failures where human wisdom, financial strength, and willpower prove entirely insufficient. Often, we attempt to overcome our spiritual deficiencies by trying harder, working longer, or comparing ourselves to others. Yet, the harder we strive in our own strength, the more exhausted and defeated we become. In Luke 18, Jesus systematically dismantles the illusion of human self-sufficiency. He encounters self-righteous religious leaders, wealthy rulers, and helpless beggars to show that human capability can never earn eternal life or fix our brokenness. The glorious message of the Gospel is that where human effort reaches its end, God's almighty power begins. What we could never achieve for ourselves, God graciously accomplishes through Jesus Christ.
Main Scripture
Luke 18:27
But he said, “ The things which are impossible with men are possible with God.”
Luke 18:27 serves as the theological hinge for the entire chapter. When the disciples heard Jesus declare how difficult it was for a rich man to enter the Kingdom of God, they asked in astonishment, 'Then who can be saved?' Jesus responded with this foundational truth: 'The things which are impossible with men are possible with God.' This verse explicitly defines the boundary of human limit and the limitless scope of divine power. In the context of salvation, moral transformation, and kingdom citizenship, human merit is completely bankrupt. salvation is not a joint venture between human goodness and divine aid; it is a divine miracle from start to finish. Jesus highlights that entering God's Kingdom is an utter impossibility for fallen humanity, but through sovereign divine grace, God regenerates hearts, breaks the power of sin, and grants eternal life to those who trust in Him.
Main Sermon Points
1. Abandon the Illusion of Self Sufficiency
The Pharisee stood and prayed by himself like this: ‘ God, I thank you that I am not like the rest of men: extortionists, unrighteous, adulterers, or even like this tax collector. I fast twice a week. I give tithes of all that I get.’
The Pharisee approached God relying on his own moral checklist and religious status, looking down on others while remaining blind to his own spiritual bankruptcy.
Scripture affirms that no person will be justified by the works of the law, establishing that human righteousness is completely incapable of earning divine acceptance.
Self-righteousness is one of the most subtle barriers to receiving God's grace. The Pharisee in Jesus' parable performed commendable religious actions—fasting and tithing beyond the requirements of the law. However, his trust was in his performance rather than in God's mercy. Because he believed he was spiritually healthy, he felt no need for a Saviour. His prayer was merely self-congratulation disguised as devotion.
Believers must actively audit their hearts for moral pride and spiritual comparison. Stop measuring your spiritual standing by comparing yourself to neighbors, colleagues, or felllow church members. Acknowledge that your best moral efforts can never satisfy God's holy standards. Shift your confidence away from your accomplishments, religious heritage, or church activity, and place it entirely on Christ.
Quick Insights
- Self-righteousness blinds the heart to its urgent need for divine mercy.
- Comparing your morality to others creates a false sense of spiritual security.
- Human effort can perform religious duties but cannot clean a sinful heart.
2. Cry Out for Unmerited Divine Mercy
But the tax collector, standing far away, wouldn’ t even lift up his eyes to heaven, but beat his chest, saying, ‘ God, be merciful to me, a sinner! ’ I tell you, this man went down to his house justified rather than the other; for everyone who exalts himself will be humbled, but he who humbles himself will be exalted.
The tax collector recognized his complete unworthiness, offering a simple prayer for mercy that resulted in immediate divine justification.
The tax collector stood far off, expressing profound reverence and grief over his sin. He offered no excuses and listed no achievements. His cry for mercy appealed directly to God's sacrifice and atonement. Jesus declares that this broken man went home justified—declared righteous before God. Divine justification is granted not to those who claim to deserve it, but to those who humbly confess their utter need for grace.
Approach God daily with complete honesty regarding your weaknesses and sins. In prayer, lay aside all defensiveness and pretense. Confess your transgressions freely, trusting that God delights in pardoning the humble. When facing overwhelming struggles, financial crises, or moral failures, imitate the tax collector by casting yourself entirely upon the boundless mercy of God.
Quick Insights
- God rejects the proud but pours out overflowing grace upon the humble.
- True repentance offers no self-defense and pleads only for divine mercy.
- Justification is a gift received through faith, not a reward earned by merit.
3. Receive the Kingdom with Childlike Trust
Jesus summoned them, saying, “Allow the little children to come to me, and don’ t hinder them, for God ’s Kingdom belongs to such as these. Most certainly, I tell you, whoever doesn’ t receive God ’s Kingdom like a little child, he will in no way enter into it.”
Jesus teaches that kingdom entrance requires the helpless dependence and uncluttered trust characteristic of young children.
Children in the ancient world possessed no social status, legal influence, or financial leverage. They were entirely dependent upon others for life and nurture. By holding up young children as the model for kingdom citizenship, Jesus highlights that salvation must be received as an unearned gift. A child does not attempt to buy or earn a parent's care; they simply receive it with helpless, complete trust.
Surrender the need to control every outcome in your spiritual life, family, and career. Approach your Heavenly Father with simple, complete trust, believing His promises even when circumstances appear difficult. Release the worldly pressure to maintain an image of self-reliant strength, and embrace the freedom of being an utterly dependent child of God.
Quick Insights
- Entrance into God's Kingdom requires laying down all human credentials.
- Childlike faith rests entirely in the character and strength of the Father.
- Salvation is an undeserved gift to be received, not a contract to be negotiated.
4. Surrender Everything to Follow Jesus Christ
When Jesus heard these things, he said to him, “ You still lack one thing. Sell all that you have and distribute it to the poor. Then you will have treasure in heaven; then come, follow me.” But when he heard these things, he became very sad, for he was very rich.
Jesus exposed the rich ruler's heart idol, demonstrating that love for wealth prevented him from embracing true discipleship.
He said to them, “ Most certainly I tell you, there is no one who has left house, or wife, or brothers, or parents, or children, for God ’s Kingdom’s sake, who will not receive many times more in this time, and in the world to come, eternal life.”
Jesus promises eternal rewards and temporal spiritual abundance to all who willingly surrender earthly securities for His kingdom.
The rich young ruler was morally upright and earnest, yet his heart was chained to his possessions. Wealth was his ultimate security and true idol. When Jesus commanded him to sell everything and follow Him, the man walked away sad. Jesus revealed that human effort cannot overcome heart idolatry; it takes a miraculous work of God to free a heart from loving created things more than the Creator.
Identify anything in your life that competes with Jesus for supreme devotion—whether money, business success, social status, or personal autonomy. Hold all earthly treasures with an open hand, placing your possessions and plans entirely at the disposal of King Jesus. Trust that whatever you sacrifice for the sake of Christ will be repaid with eternal life and incomparable spiritual joy.
Quick Insights
- Jesus demands total allegiance, exposing every idol that occupies His place.
- Earthly riches become a deadly trap when they replace trust in God.
- Sacrifice for the Kingdom of God is always rewarded with eternal abundance.
Bottom Line
Salvation and true spiritual victory are entirely impossible through human strength, but fully accomplished by the sovereign power and grace of God.
Memorable Quote
Where human effort reaches its natural end, God's sovereign grace reveals its supernatural power.
Theological Point
The primary doctrine taught in Luke 18 is justification by grace through faith alone, coupled with the absolute necessity of divine regeneration. Fallen humanity is spiritually dead and utterly incapable of saving itself, keeping God's law perfectly, or surrendering its heart idols through innate willpower. Salvation is a monergistic work of God, wherein divine grace humbles the proud, grants spiritual vision, transforms human desires, and accomplishes what is humanly impossible.
Prayer Guide
- Pray for a humble heart that rejects all forms of self-righteousness and spiritual pride.
- Ask God to reveal and eradicate any subtle idols competing with total devotion to Christ.
- Thank God for accomplishing through His grace what our human striving could never achieve.
- Seek God's help to trust Him like a child in every difficult circumstance and decision.
Responding to God’s Word
Returning to our title, Impossible with Man, Possible with God, we are reminded that the Gospel is good news precisely because it announces what God has done where we have failed. Human striving can never erase sin, satisfy divine justice, or conquer the human heart's stubborn pride. If salvation depended on our strength, we would be hopelessly lost. But praise be to God, Jesus Christ came to do what was impossible for us. He lived the perfect life we could not live, took our punishment upon the cross, and rose victorious from the dead to secure our redemption. Whether you are struggling under the weight of guilt, battling persistent trials, or seeking freedom from earthly bondage, turn your eyes to the Saviour. Stop trying to earn what can only be received as a gift. Cry out for His mercy, yield your whole life to His lordship, and watch God accomplish His impossible, glorious work in you.
