Summary: The world calls it foolishness. The preaching of the Gospel is the power of God.
It is a foolish thing to preach a sermon. When you stand up and tell people that they are lost and that their only hope of salvation rests in the crucifixion and resurrection of Jesus that in the world’s way of thinking is foolishness.
Not that standing before people and talking is foolishness. The top universities use this as a chief method of teaching. It’s the cross that is nonsense to the world.
Preaching the cross is not actually foolish. It only seems foolish to many. But it pleases God to demonstrate His power by the foolishness of preaching. (1 Corinthians 1:21)
Preaching the gospel is not foolish. No. The foolishness of God is wiser than man’s wisdom. The weakness of God is stronger than man’s strength (1 Corinthians 1:25).
For the one who is wise in the world’s wisdom the cross is crude and unscientific. They think it is foolish. Preaching the Gospel is the power of God to those being saved. These verses record Peter’s Pentecost sermon. This passage Acts 2:14-41 demonstrates the great power in preaching the gospel.
This is a Pentecost sermon because this day that Peter preached was Pentecost. This was the Jewish feast celebration. On this day Jews from all over the Diaspora (dispersion) had come to Jerusalem.
The festival of Pentecost is celebrated fifty days after Passover. On this occasion of Pentecost:
50 days earlier Jesus was crucified in Jerusalem.
47 days earlier Jesus resurrection took place.
10 days earlier Jesus ascended to heaven.
The early believers were told to wait for the promised Holy Spirit to come. Now only 120 believers are gathered waiting as Jesus instructed them.
Suddenly a sound like the violent blowing wind came from heaven and filled the whole house where they were sitting. They saw what seemed to be tongues of fire that separated and came to rest on each of them. All of them were filled with the Holy Spirit and began to speak in other tongues as the Spirit enabled them.
The great sound attracted a crowd of Diaspora Jews. They were amazed that they each heard them speaking in their own language.
The people thought they were drunk (Acts 2:13). If you can’t understand it, slander it. But Peter stood up to tell them what was happening. This was the same man who just 51 days earlier rebuked Jesus for talking about his death. But now Peter is preaching that death.
Peter saw the resurrection and is now filled with the Holy Spirit. Now with boldness he preached the cross of Christ. God demonstrated that such preaching is the power unto salvation. For the message of the cross is foolishness to those who are perishing, but to us who are being saved it is the power of God (1 Corinthians 1:18).
The first thing Peter did when he stood to address the crowd was to set the record straight. These men are not drunk as you suppose. It’s only nine in the morning! (Acts 1:15)
They all knew that Jesus was crucified. What he must convince them of is that Jesus was the promised messiah and that God resurrected Him.
Peter Preached his Personal Experience.
