Great question! The Great Commission is a natural outworking of the story of God. It is not a brand new idea, nor anything Jesus came up with. It is congruent with the OT story and direction. For example, when Jesus tells his disciples he will make them fishers of men, he is not being clever or punny, since they were fishermen. No. He is fulfilling the OT understanding from Jeremiah 16, that Yahweh would send out fishers (and hunters) to gather the exiles from the nations.
What do you mean by if the church knew the story of God, it would know what to do minus Matthew 28?
