Acts 20:25

Paul continued by laying out his plans for the future. The kingdom Paul preached is God’s rule over His elect. It probably includes His spiritual rule now and His messianic rule during the Millennium.

"Usually in the book of Acts the kingdom of God refers to the eschatological realm of salvation (Acts 14:22). But in this passage, the kingdom of God is the summary of Paul’s entire message in Ephesus and refers to the present blessings of redemption in Christ." [Note: Ladd, "The Acts . . .," p. 1163.]

"Paul clearly equated preaching the Gospel of the grace of God with the preaching of the kingdom of God. Once again [cf. Acts 20:22-24] we see that the two terms are used interchangeably [cf. Acts 28:23; Acts 28:30-31]. . . .

"Thus as we survey Paul’s ministry as recorded in the Book of Acts, we see that he was an ambassador of the kingdom of God-but his message was salvation through the death and the resurrection of Jesus Christ. No reference is made to support the notion that the earthly Davidic kingdom had been established. Rather, the message concerns entrance into a present form of the kingdom of God by faith in Jesus Christ." [Note: Pentecost, Thy Kingdom . . ., p. 280.]

Paul was confident that all the men he addressed would not see him again, though some of them might. He did not plan to return to Ephesus for some time if ever (cf. Romans 15:23-29).
