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.
