You obviously haven't been paying attention to the numerous posts by the avid FWers here. To them, God is not an actual Savior since there is no efficacy to his grace. All God does is provide the sons of men with opportunities to save themselves, since it is their "freewill" that actually efficacious. So...of what value is there in God "moving hearts to believe" when there is zero efficacy in that power?
Or where was this "synergism" (so called) in the Garden when God sovereignly decreed to reconcile Eve unto himself, while simultaneously omitting Adam from that decree? Or where was it when God decreed in eternity to make Issac and Jacob participants in the Abrahamic Covenant, while simultaneously excluding Ishmael and Esau from the Covenant? Or where is the ring of synergism in God sovereignly choosing who He will have mercy and compassion on, since salvation does not depend on the man who wills or exerts himself (Rom 9:16). Or where was synergism when God rescued and redeemed the helpless Israelites in Egypt? Or where is the synergism in Peter's confession of faith? Or where was synergism when Jesus raised Lazarus from his tomb? (Oh wait...this last one doesn't count since mankind is not dead to God, and since man isn't spiritually dead, then man's own natural will power is sufficient unto salvation!) The only people on this thread that acknowledge and confess to God's supernatural power in salvation are the believers in the Doctrines of Grace.
Plus, I find your explanation now more than disingenuous since several weeks ago you yourself proclaimed that it is sinners themselves who make the difference when one group accepts the gospel and the other one does not. You didn't even give God an honorable mention! But now all of a sudden He "moves hearts" -- HEARTS no less!? What in the world does a man's heart have to do with his volition!? Salvation is all about MAN'S volition, volition, volition, volition in Pelagianism, Arminianism, or Freewillism -- whichever term floats your boat.
