V.1-18 Peter is blamed at Jerusalem for associating and eating with Gentiles. They had not yet learned what Peter had. He rehearses God’s acts in the whole incident. They could not resist his testimony. The believing Gentiles have been brought in, and made one with the believing Jews! Wonderful fact! The truth of the one body is received.
V.19-26 The gospel goes far and wide now. The Gentiles receive the Lord Jesus as their Savior. The light of Christ is now starting to light up the civilized world. In very little time, Paul takes it through the Roman Empire, and assemblies are established over a vast area.
V.27-30 Now the everyday problems are real, and Christianity has great care for the needs of other believers.
