The Book of Acts records the missional work of God in various cities in the Roman Empire. Acts 3 is the story of a healing, the people praising God, and Peter’s clarification of what God is doing. As we read the Book of Acts in search of missional theology, we are reading The Acts of the Apostles (Abingdon New Testament Commentaries)
as our guide.
Again, event leads to Word, miracle leads to explanation — by Peter. First, Peter witnesses to Jesus as the Author of Life at work in the healing; second, God is now giving them a chance to respond prior to the Second Coming, and third:
For Moses said, ‘The Lord your God will raise up for you a prophet
like me from among your own people; you must listen to everything he
tells you. Anyone who does not listen to him will be completely cut off from among his people.'”Indeed, all the prophets from Samuel on, as many as have spoken, have foretold these days. And you are heirs of the prophets and of the covenant God made with your
fathers. He said to Abraham, ‘Through your offspring all peoples on
earth will be blessed. ‘When God raised up his servant, he sent him first to you to bless you by turning each of you from your wicked ways (Acts 3:22-26).
Peter challenges his readers with this: you are in God’s people, Israel, if you respond to Jesus as Messiah.
Missional gospel emerges out of and is nested in the Story of God with Israel. The prophetic witness is a witness to Christ — missional witness then is only properly missional when it witnesses to Jesus as the climax of Israel’s Story. Social justice, in other words, is not enough. Missional is only properly Christian when it gets connected to Jesus.
