From a worldly perspective, Christ's death signaled His defeat. After all, dying in agony on a cross hardly seems like the path to victory. But it was! And He did it all for us. Because Jesus triumphed over death, we can be victorious in life. Just consider what He won for us by sacrificing Himself on the cross.
Our Eternal Salvation: The cross was the means of our salvation. Without it, we'd have no hope of heaven. If Christ hadn't died in our place, we'd have to stand before God and receive the just punishment for every sin we've ever committed.
Power over Sin: Jesus not only paid the penalty for our sin; He also brought us present victory over it. When He was crucified, our old sinful nature died with Him (Rom. 6:6). The power of the "flesh" was broken, and Jesus now lives His triumphant life through us. That means we are no longer enslaved to sin and can choose obedience to God.
Defeat of Satan: At the crucifixion, the list of decrees against us was nailed to the cross, and the Devil lost his power over our lives (Col. 2:13-15). None of his accusations can stick, because God holds nothing against us anymore. And now every time we yield to the Spirit within us, Satan is defeated once again.
Christ met all our needs on the cross. By making us a part of His family, He gave us a sense of belonging. When He died in our place, He affirmed our value. And by coming to live His life through each believer, He gives us the ability to live a victorious, obedient life.
