During the time Jesus was tried, crucified, buried, and resurrected from the dead, Peter was living a tumultuous life on earth. However, something happened in Peter’s life after the roller coaster ride of denial of his Lord. For forty days Jesus lived with the disciples prior to His ascension into heaven. For ten more days, the disciples stayed in Jerusalem, waiting and praying. Some have suggested that the new power in Peter’s life was his knowledge of the resurrection of Jesus Christ.
Unquestionably, that was a thrilling thing to know; but it was not the key to Peter’s consistent spiritual victory. He had known about the resurrection for all but three days of those seven weeks and had experienced no new power. The “secret” was what Peter and the other disciples were waiting and praying for during those ten days in Jerusalem. The Lord Jesus Christ Himself, before He ascended into heaven, had said to them in Acts 1:8, “But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth.“
The new power in Peter’s life was not the result of something: it was the result of Someone – the Holy Spirit. Once Peter was controlled by the Holy Spirit, he became a powerhouse for his Lord. No longer did he have to rely on his own abilities to motivate and lead others. Now he was charged with the very power of God Himself. Of course, Peter sinned and blundered even after his discovery; but these failures were the exception, not the rule.
Maybe you are riding a spiritual roller coaster like the one Peter rode for such a long time. You want to get off, but you do not know how. Take heart, because you can experience in your life the same transforming power that changed Peter from an unpredictable disciple to the “rock” of the early church.
