Acts - A Second Volume Tired to the Gospel of Luke

Luke is written more of the new testament than any other writer. He's trying to explain how what appears to be a new religious movement is actually a quite old movement. Christianity appeared to be the new thing on the block, and it was attempting to bring jews and gentiles together. And so luke is really the story how the gospel was intended to be for all people - from the time god made his covenant commitments to abraham.
