Why did the Jewish believers come in by the Kingdom Gospel while Paul went in a different direction?
Jewish believers entered through the Kingdom economy and Kingdom Gospel, but Paul moved in a different direction because his ministry was not under Law but under Grace. It was not opposition to Jesus' teachings but an extension of them, serving the same God and same Christ, especially as prisoner for the Gentiles.
Les explains that the Jewish believers had come in by virtue of the Kingdom economy and the Kingdom Gospel, yet Paul was now going in a different direction while still serving the same God. Les warns not to lose sight of this, because some theologians claim Paul contradicted Jesus. Les says it is not opposition but a difference: not under Law but under Grace, same God and same Christ. Paul's statement in Ephesians 3:1 as prisoner of Jesus Christ for the Gentiles shows his teaching extends Jesus' teachings rather than opposes them.
