Most of Acts chapter 2 contains Peter’s gospel sermon. It was at this time God kept His promise to establish the Messianic kingdom, and was the first time the declaration of the ratified gospel of Jesus was preached.
As such it is a significant event and significant message. In examining the first part of the lesson, we note first of all the gospel is proclaimed to be heeded by men (cf. Romans 1:16; 10:17). While some were wrongly thinking that these men who were preaching in tongues were drunk (cf. vs. 13), Peter revealed what was actually in play.
Their baptism in the Holy Spirit and the signs accompanying this event was prophesied in the Old Testament, and Peter brings their minds to this passage (cf. Joel 2). Not only was this a sign that the apostle’s words were to be obeyed, but it also was an indication that God’s ultimate blessing to all men had come. “whoever calls on the name of the Lord shall be saved” (vs. 21).
