The Power of the Cross
Luke 23:32–34
"And there were also two other, malefactors, led with him to be put to death. And when they were come to the place, which is called Calvary, there they crucified him, and the malefactors, one on the right hand, and the other on the left. Then said Jesus, Father, forgive them; for they know not what they do. And they parted his raiment, and cast lots."
For just a few minutes today, I want to preach from the subject, "The Power of the Cross." Church, if we're not careful, life can become so busy that we forget about the very thing that gave us life. We have jobs to work, bills to pay, families to care for, appointments to keep, problems to solve, and plans we're trying to put together. We spend so much time running from one responsibility to another that sometimes the cross becomes an afterthought instead of our foundation. But without the cross, there would be no Christianity. Without the cross, there would be no church, no salvation, no forgiveness of sin, no hope of heaven, and no promise of eternal life. Everything we believe, everything we preach, and everything we celebrate rests upon what Jesus Christ accomplished at Calvary. The cross is not just a symbol we wear around our necks or place on top of a church building—it is the very heart of our faith, and there is still power in the cross of Jesus Christ.
We live in a world that is obsessed with power. Nations fight for power, governments compete for power, businesses chase power, and people will sometimes lie, cheat, manipulate, and even hurt others just to feel important or stay in control. But real power does not come from money, titles, influence, or position; real power comes from God. At Calvary, Jesus did for us what we could never do for ourselves. We could never earn salvation by good works, religious activity, or our own righteousness. We could not clean ourselves up enough or pay the debt that sin demanded. So Jesus willingly suffered in our place. He was beaten, mocked, humiliated, wounded, and ultimately crucified for our sins and for the sins of the whole world. Yet even with all power at His command, He refused to come down from the cross because His love for us was greater than His desire to escape the pain. The nails did not hold Him there—love held Him there. Grace held Him there. Mercy held Him there. His determination to save lost humanity held Him there. And that is why, after more than two thousand years, there is still life-changing, soul-saving, wonder-working power in the cross of Jesus Christ.
The Cross Shows Us the Seriousness of Sin
When Jesus was led to Calvary, He was not alone. Two criminals walked beside Him, one on His right and one on His left. Jesus was placed in the middle as though He were the worst of them all, yet He had never committed a single sin. He never lied, cheated, stole, or mistreated anyone. Instead, He healed the sick, opened blind eyes, fed the hungry, comforted the brokenhearted, and preached the truth. Yet He was condemned like a criminal because He willingly took our place. The punishment belonged to us, but Jesus accepted it. The shame belonged to us, but He carried it. The debt was ours, but He paid it. The cross reminds us that sin is not just a mistake or a bad habit; sin separates us from God and leads to death. Every lie, every act of pride, every hidden struggle, and every act of rebellion was placed upon Jesus. The cross shows us how serious sin is, but it also reveals that God's love is greater than our sin.
The Cross Shows Us the Depth of God's Love
Jesus was never trapped on the cross. At any moment He could have stepped down. The One who commanded the winds and waves could have spoken one word and ended it all. The One who called Lazarus from the grave could have called legions of angels to His rescue. Yet He remained on that cross because He knew that without His sacrifice we would remain lost forever. Love—not nails—held Him there. Every insult, every blow, every thorn, and every nail was endured because of His great love for us. The cross is God's declaration that no one is beyond His love. Even before we knew Him, He knew us. Before we ever called His name, He had already made a way for our salvation. Whenever life makes you feel forgotten, rejected, or unworthy, look at the cross. It reminds us that we are deeply loved by God.
The Cross Has the Power to Forgive
One of the greatest demonstrations of power was not found in a miracle but in the words Jesus spoke while hanging on the cross. Looking at the very people who mocked Him, beat Him, and nailed Him there, Jesus prayed, "Father, forgive them; for they know not what they do." Most people would have prayed for revenge, but Jesus prayed for mercy. That is divine power. The cross teaches us that forgiveness is possible even when the pain is real. Forgiveness does not excuse what someone has done, nor does it mean pretending the hurt never happened. It means placing the matter into God's hands and refusing to allow bitterness to control your heart. The same grace that forgave us gives us the strength to forgive others.
The Cross Has the Power to Save
The cross reaches farther than human failure. It has the power to save the liar, the thief, the addict, the broken, the ashamed, and the person everyone else has given up on. Jesus was crucified between two criminals, reminding us that He came for guilty people. One of those criminals placed his faith in Jesus during his final moments and was promised a place in paradise. He had no opportunity to make up for his past, join a church, or prove himself worthy. All he could do was trust Jesus, and that was enough. Salvation is not earned by good works but received by grace through faith. The cross declares that no one is too far gone and no life is beyond the reach of God's saving power.
The Cross Reconciles Us to God
Because of the cross, the relationship that sin destroyed has been restored. We were separated from God, but through Jesus Christ we have been brought near. We were guilty, yet through His sacrifice we have been justified. We no longer have to live under condemnation because Jesus paid our debt in full. Through faith in Christ, we now have peace with God and can come boldly before His throne whenever we need mercy or grace. He knows our struggles, our tears, and our weaknesses, yet He still welcomes us into His presence. That is the wonderful power of the cross.
You Have to Be Willing to Carry the Cross
Jesus carried His cross to Calvary, and every believer is called to carry his or her own cross by following Him daily. Nobody can believe for us, surrender for us, or walk with God in our place. The cross reminds us that every one of us was a sinner in need of the same Savior. At Calvary there is no room for pride because the ground is level at the foot of the cross. The rich need Jesus, the poor need Jesus, the preacher needs Jesus, and every person sitting in the pew needs Jesus. Because of His sacrifice, darkness no longer has the final word. Sin does not have the final word. Jesus Christ has the final word.
The Cross Has the Power to Change Us
A genuine encounter with the cross changes everything. When we truly understand what Jesus suffered for us, we cannot continue living as though His sacrifice means nothing. The cross changes the way we speak, the way we think, the way we treat people, and the choices we make every day. It produces humility where pride once ruled, forgiveness where bitterness once lived, and gratitude where selfishness once reigned. We do not live right in order to earn salvation; we live right because Jesus has already secured our salvation. The cross transforms sinners into saints and lost people into children of God.
The Cross Inspires the Faithful to Fight On
Life will bring trials, disappointments, sickness, heartbreak, and moments when we do not understand what God is doing. Yet the cross reminds us never to give up. When we look at Christ crucified, we remember that suffering is not the end of the story. We keep believing, keep praying, keep trusting, and keep pressing forward because God has already shown us through Calvary that He can bring victory out of what looks like defeat. When your heart is heavy, hold on to God. When your strength is low, hold on to God. When your burdens seem too great to bear, remember His Word: "Casting all your care upon Him; for He careth for you." The cross gives us the courage to keep fighting because we know that God is faithful.
Closing Prayer
Heavenly Father, we thank You for the power of the cross. Thank You for sending Your Son, Jesus Christ, to suffer, bleed, and die for our sins so that we might have forgiveness, hope, and eternal life. Help us never to forget the price that was paid at Calvary. Let the cross change our hearts, strengthen our faith, and remind us every day of Your amazing love and grace.
Lord, as we leave this place, help us to carry our cross faithfully and live in a way that honors You. Give us strength to forgive, courage to trust You, and power to stand when life becomes difficult. If there is anyone here who has not yet accepted You as Savior, touch their heart before it is too late. Keep us in Your care until we meet again, and may everything we do bring glory to Your name. In the mighty name of Jesus we pray. Amen.
