"The Gospel of the Kingdom" was preached to Israel until it was blinded for its rejection. That good news is not to be preached again until the time of the second appearing of King Jesus to Israel, when the gospel of the Kingdom will again be preached in all the world to Israel.

For the past 1950 years or so it has been "the Gospel (good news) of the Grace of God” (Acts 20:24) that is to be preached to sinners, both of Israel and the Gentile nations. Failure to understand the distinction between the gospel of the Kingdom and the gospel of Grace has caused all of the divisions we see among Christianity. The gospel of grace has nothing to do with the Old and New Covenants between God and Israel.

“I am speaking to you who are Gentiles. Inasmuch then as I am an apostle of Gentiles…For I do not want you, brethren, to be uninformed of this mystery—that a partial hardening has happened to Israel until the fullness of the Gentiles has come in; and so ALL ISRAEL WILL BE SAVED; just as it is written, ‘the Deliverer will come from Zion, He will remove ungodliness from Jacob. This is My covenant with THEM, When I take away their sins’… for the gifts and the calling of God are irrevocable. For God has shut up all in disobedience so that He may show mercy to all.” (Romans 11:13-32)

God has promised to save ALL Israel. And He has promised to save ALL mankind….and that brings a special joy to those who hear and believe what God has promised.

“It is a trustworthy statement deserving full acceptance. For it is for this we labor and strive, because we have fixed our hope on the living God, who is the Savior of all men, especially of believers. Prescribe and teach these things” (1 Timothy 4:9-11)
