This was one of the best articles I read while studying at Ridley. In it God confirmed a bunch of important theological realities and took them even further. Peterson’s commentary on Acts is excellent, but this article will give you a great overview connecting ascension, promise-fulfillment, Christology and the Kingdom of God:
