When Peter began following Jesus, he was unstable and insecure. Yet Jesus changed his name from Simon to Peter—“rock”—because He saw his potential. Peter failed miserably and denied Jesus. But Jesus restored him, and he was filled with the Holy Spirit on the day of Pentecost. He was transformed by grace! When you read his first epistle you see that he became an apostle (1 Peter 1:1) and strong spiritual father. He wrote his letter to “newborn babies,” and he challenged them to “grow” (2:2).
This is what God will do through you. Don’t focus on your flaws. Grace will change you. Just as Peter was transformed, you will become a disciple-maker. Peter says God will “perfect, confirm, strengthen and establish you” (5:10). And at the end of his letter Paul mentions his “son,” Mark (5:13). This is the same guy who wrote the book of Mark! God can make you a strong leader and give you disciples who will preach the gospel with power. Expect that to happen!
