Peter: A Case Study in Maturity

In the first post of this series, we studied Peter’s weakness the night before Jesus was crucified. After Jesus’ arrest, the crowd questioned Peter about his association with Him. All three times, Peter denied his Lord. Peter was weak when Jesus—his major source of spiritual influence—was taken away from him. He buckled when pressured by the crowd. And when forced to choose his true allegiance, he denied knowing Jesus Christ.

After that tragic night, Peter goes on to do great things for his Lord. Much of the first half of the book of Acts features Peter as its main character. He also pens two books of the New Testament. Peter’s sermon at Pentecost in Acts 2 jump-starts this post-resurrection greatness.

At Pentecost of Acts 2, notice that Peter’s faith stood strong when…

Jesus was taken away—for good—from His disciples (Acts 1:6-10). Fifty days prior to this account, Peter acted immaturely and denied knowing Jesus. Now, Jesus has died and resurrected. He is back spending time with the apostles and disciples. In Acts 1, however, we read that Jesus ascends to heaven to be with the Father until His second coming (Matt. 25:36-37). This is more significant than being arrested and taken away to trial. This is final.

Notice how Peter responds after Jesus leaves this time. First, he leads the effort to replace Judas with Mathias (Acts 1:15ff). Then, at Pentecost, he preaches that Jesus is the Christ, and some 3,000 souls are baptized for the forgiveness of sins (Acts 2:14-41). Though Peter no longer had his major source of spiritual influence, he exercised spiritual strength by introducing a multitude of souls to their Savior. As Jesus had comforted Peter and the apostles, He comforts us today, “And behold, I am with you always, to the end of the age” (Matt. 28:20).

Some in the crowd were pressuring the disciples (Acts 2:5-13). Peter denied knowing Jesus when the crowd approached him directly. He gave in to peer pressure. Here, in Acts 2, we see pressure from some in the audience that day. Through the Holy Spirit, the apostles were doing unbelievable things (Acts 2:1-12). They were so unbelievable that some mockingly accused the apostles of being drunk!

The apostles could avoid embarrassment by not speaking in tongues. Peter could preach an easier message to the Jewish crowd that Jesus was not the Messiah. Peter also could ignore the insults hurled by the audience. Instead, Peter and the apostles display great courage by confronting their erroneous claims (2:14-15) and by preaching the truth about Jesus Christ (2:16-41).

He was forced to choose his allegiance (Acts 2:14-39). In Matthew 26, Peter could not ride the fence regarding his association with Jesus. He could only answer “yes” or “no” (“present” was not an option). In Acts 2—before an anti-Jesus crowd—he had to choose if and how strongly to preach the saving message about Jesus. Based on how the people previously handled Jesus, they could kill Peter just the same. If a violent disturbance broke out, the apostles and disciples were clearly outnumbered. On this occasion, Peter boldly tells the people “God has made him both Lord and Christ, this Jesus whom you crucified” (Acts 2:36).

Even though the truth would be difficult for some to accept, he proclaimed it anyway. His faith in Christ was strong and his actions prove it. Like Peter, we will face situations where our faith and allegiance are tested. We must choose Christ anytime and every time. Peter made a dramatic turnaround from his denial of Jesus to his sermon on Pentecost.

Next time, we’ll look at what made the difference for Peter and can make the difference for us today.
