Christ died to enable us to live by faith in Him, not in ourselves. Galatians 2:20 reminds us that our old self was crucified with Christ, and now Christ lives in us. As new creations (2 Corinthians 5:17), we no longer live for ourselves but by trusting in the Son of God, who loved us and gave Himself for us. This new life means we no longer depend on our own strength or desires—we remember Christ daily, live by faith in His power and promises, and show our love for Him through obedience (John 14:23-24). His death gives us the joy and purpose of living for Him.

Jesus died so that we would stop boasting in ourselves and start boasting in Him. The cross shows us that salvation is not earned by our works, wisdom, or strength—it is entirely a gift of God's grace. Christ alone lived a perfectly righteous life, and His righteousness is given to all who trust in Him. That’s why the only thing worth boasting about is the cross. It humbles us, lifts up Jesus, and reminds us that in our weakness, His power is made perfect.

Jesus gave Himself for our sins to rescue us from the deception of this present evil age. Satan blinds people to the gospel, using the world’s lies and temptations to keep them in sin (2 Corinthians 4:3-4). But Jesus’ death was His victory over Satan, breaking his hold and freeing us from sin and the fear of death (John 12:31-32, Hebrews 2:14-15). As believers, we must reject the world’s false wisdom and follow Christ, whose cross brings true freedom and salvation to all who believe (1 Corinthians 3:18-19, 1 Corinthians 1:23-24).
