Unconditional Election
Unconditional Election is the doctrine which states that God chose those whom he was pleased to bring to a knowledge of himself, not based upon any merit shown by the object of his grace and not based upon his looking forward to discover who would "accept" the offer of the gospel. God has elected, based solely upon the counsel of his own will, some for glory and others for damnation (Romans 9:15,21). He has done this act before the foundations of the world (Ephesians 1:4-8).
Where does this leave free will? God chose some for damnation at the start of the universe, there is no hope for them. They will not hear the Gospel, or if they do will not accept it, or if they do will not be saved?
