God has promised that anyone who will put aside his/her own biases, with an honest and open heart, can come to Him for wisdom and understanding. You begin and end with the Bible. This discussion about the existence of fire and brimstone and whether or not God is an egomanical psychopath is pointless until you do. One can try to muddy the waters by arguing about the translations and what He plainly said, but you cannot get away from the clear meaning: God will absolutely punish unrepentant sin. By the grace of Christ, He has taken our penalty, if we accept it. That is our choice- either we accept His atoning sacrifice, or we pay our own penalty.
