I do not believe in Dual Covenant Theology. Jesus said, “I am the way and the truth and the life. No one comes to the Father except through me” John 14:6. Messianic Jews are part of the church, so they are saved. The scriptures also say that God has a covenant with the Jews and Israel. Although the church age Jews have not acknowledged Jesus as their Savior and therefore are not saved, God has brought them back to the land of Israel. Is it because, although they have not accepted Jesus, God will always keep his covenant with them as His people, whether they believe in Jesus or not?
Basically, Dual Covenant Theology holds that Jews don’t have to accept Jesus as their Savior under the New Covenant, because they’ve already been saved under the Old Covenant. This view can not be supported by Scripture and in fact contradicts the words of the Lord in John 14:6.
In his prophecy of Israel’s latter day regathering, Ezekiel indicated that at first they would not be a nation of believers. Their official “awakening” will not be complete until after the Battle of Ezekiel 38-39 but even that will only bring them back to their Old Covenant relationship with God. The realization that Jesus is their Messiah will happen toward the end of the Great Tribulation and is described in Zechariah 12:10. When the Lord returns to establish His Millennial Kingdom on earth, all the inhabitants of Israel will have come to the realization that Jesus is their Messiah and will worship Him as their Lord.
