I Timothy 2:3-4 tells us that God wants all men to be saved and to come to knowledge of the truth.  But it also tells us in Romans 1:20, “For since the creation of the world God’s invisible qualities – His eternal power and divine nature –  have been clearly seen, being understood from what has been made, so that men are without excuse.”  So whether we want to admit it or not – we know what’s right and wrong.  God’s unearned and unmerited favor is for all.  But when we reject God’s truth, we become estranged from Him, having no excuse except our selfish Will.
