John 21:15, NIV: When they had finished eating, Jesus said to Simon Peter, “Simon son of John, do you truly love me more than these?” “Yes, Lord,” he said, “you know that I love you.” Jesus said, “Feed my lambs.”

Regret is often worn like a heavy anchor—it weighs us down and inhibits us from living life to the fullest. Past mistakes can haunt us as such that we will forever be trying to make up for the wrong we have done. Consider Peter, who had denied Jesus three times. It was a mistake he would have lived with the rest of his life. But Jesus restored Peter, and replaced his regret with responsibility. Jesus knew what Peter had done, but would not allow him wallow in self-pity. Peter needed to put his mistake behind him, and focus on what he now had to do. Regret can lead us to seek to redeem ourselves. But we cannot redeem ourselves at all—our redemption is only found in Jesus. Through the cross of Christ, we are not only redeemed from sin, but also from the burden of past regret.
