Amillennialism is a complicated theory, and I'm not going to pretend to understand everything it says. However, one aspect of amillennialist thinking has been on my mind a lot lately:
Amillennialism preaches that the promises made to Israel now apply to the Church; that the Nation of Israel had their chance to accept Christ, didn't, and so God will no longer deal with them. Many evangelical churches embrace this theory.
By insinuating that God will not fulfill His promises to His people, the amillennialist calls into question the very character of God. If the promises made to Israel are no longer valid, what hope do Christians have that God won't simply turn His back on the promises He's made to us? What good is a promise from God if He's free to rescind it on a whim?
God's character is consistent throughout time. Often we view Him as judgmental and stern in the Old Testament but gracious and loving in the New. But Malachi 3:6 says, "For I am the Lord, I change not..." His character is steady and unchangeable throughout eternity.
Hebrews 10:23 says, "Let us hold fast the profession of our faith without wavering; for he is faithful that promised." If God's promises are faithful and true once, then they are always true. The promises to Israel and to the Church are true because God made these promises, not because of anything we could do.
