Peter’s testimony wasn’t limited to speaking in Jesus’ presence; he continued to testify later in his life. His later statements are made all the more remarkable because of what happened the night Jesus was betrayed. (After bold predictions of loyalty, he denied even knowing Jesus during Christ’s trial at Caiaphas’ house, and left there a broken man, Matt 26:75). Following this devastating personal failure, he was restored by the resurrection and encouragement of Jesus, recorded in John 21. So it was he who stood up in Jerusalem to deliver the first sermon at Pentecost: “Men of Israel, listen to this: Jesus of Nazareth was a man accredited by God to you by miracles, wonders, and signs, which God did among you through him, as you yourselves know.”…”God has raised this Jesus to life, and we are all witnesses of the fact.” (Acts 2:22, 32, NIV) Peter, who betrayed his best friend and wept bitterly became Peter, the powerful witness. Peter the Professional Fisherman became Peter the prophet. He was not depending on his own merit to stand up and preach, he was depending on the facts about Jesus. While he lost confidence about himself, he gained confidence in Christ. Perhaps you have had some failures regarding being loyal to Jesus; the Lord knows I have over the course of my life. In fact, I have made the biggest mistakes in my life as a Christian; like Peter, I made bold promises about my commitment and then failed. But just like Peter, we can be reclaimed and restored. The amazing thing about giving testimony is that it doesn’t depend on our success or worthiness, or what we’ve accomplished. It depends on what Jesus did, and the confidence we can have in him. If there is ANY difference in your life because you know Jesus, then speak up! It’ll preach.
