The Greek words of that verse say that our salvation is δῶρον dōron: a sacrifice or gift offered to God.
If salvation has NOT been provided for EVERYONE as a free gift from God, Hebrews 2:9, then God is not just. If God is not just then how are you going to have faith in him? It is not humanly possible to have faith in a God that predestinates people to hell before they are born.
