This article argues that the plan of God played a big role in the writings of Luke and thus in the book of Acts. The author argues that the "plan of God" forms the theological basis for what Luke understood as preaching. It was God who acted through the preaching of the apostles. The preaching of the disciples is a result of God working out his plan for the nations. The plan of God also determines the content of the preaching.
