After the Holy Spirit came upon the Apostles in power, just like Jesus promised, the Apostles spilled into the streets of Jerusalem speaking in tongues. The crowds responded with wonder and amazement, while some mocked them and thought they were drunk. Peter stood up and delivered the first Christian sermon. The same man who had denied knowing Jesus just a couple of months earlier now stood with boldness, beautifully applying the texts and prophecies of the Old Testament and pointing the the supremacy of Jesus the Christ. 3,000 people were saved that day. This Sunday we begin a 3-week look at Peter's sermon, and we will see that Jesus is our Savior.
