Peter's sermon at Pentecost in Acts chapter 2 will forever be known as the sermon that propelled the Church into the future. And while we know it wasn't as much the words that he spoke as it was the Holy Spirit power behind them we would be amiss if we didn't study what God inspired into His servants heart. During the next two Sunday's we will break down the sermon into two parts. In this first part we see; I. Peter made a affirmation that the day of the Lord had arrived. (Vs. 16-21). II. Peter made a proclamation of the Gospel. (Vs. 22-24).
