ACTS 28:23 Paul must have had many precious meetings with his believing brethren. He must have made known to them those transcendent truths which he teaches in his Perfection Epistles. If the Acts were giving an account of his career or of his evangel, it stops short at the most important point. As a "history of the commencement of the Christian church" it is the most disappointing of all books, for the truths which distinguish the present economy, found in Ephesians, Philippians, and Colossians, were not made known until its close and are never referred to, much less taught. Those events in Paul's career which are of the upmost importance for present truth, from his sojourn in Arabia to the dispatch of Tychicus with the Perfection Epistles, are quite overlooked in this account. Paul's sojourn in Rome marks the beginning of that vast work of the Spirit of God which has continued down to the present time. Yet all we are told here is the disappointing meeting with the Jews! Instead of closing with a song of victory and sending the church on its triumphant way, he quotes Isaiah's doleful prophecy concerning the apostate nation, showing the failure of the kingdom proclamation and the reason why it should no longer be heralded. What stronger evidence is needed to show that the Acts is not concerned with the so-called "church"? It is no mere history of the apostolic times. It is concerned only with those events which chronicle the fortunes of the earthly kingdom. It deals with a transitional period when the church was still dependent on the favored nation and had a subordinate place in the reign of Messiah over the earth, as promised by the Hebrew prophets.
