And the people gathered also from the towns and hamlets around Jerusalem, bringing the sick and those troubled with foul spirits, and they were all cured. - Acts 5:15–16
Peter was a man with a past. He was bold and not afraid of change, but he also had many faults. In Matthew 16:22–23, we see Peter trying to correct Jesus. In Matthew 26:31–35, we see that Peter thought more highly of himself than he should have. In Matthew 26:69–75, it is recorded that Peter denied even knowing Jesus.
Once Peter realized the depth of his sin, he wept bitterly, which showed that he had a repentant heart (v. 75). God is merciful and understands our weaknesses. In John 21, we see Jesus lovingly restore Peter. Peter had been included in God's plans for the future even though he had a past record of foolishness and failure. Peter had denied Christ, and yet he became one of the best-known apostles. Peter could have spent his entire life feeling bad about his denial of Jesus, but he pressed past that failure and became valuable to God's kingdom.
Lord, You are a God of transformation. Help me to press past my failures and become a valuable servant of Yours today. Thank You for including me in Your plans for the future. Amen.
