Many men do not believe. Many men hate the Cross because it means a salvation not of their own choosing or making, but rather of God’s grace and his mercy. Men hate the cross because it means a salvation which is unearned, undeserved, unmerited. Men would much prefer God to punish them than to forgive them because that would mean that God is dependent upon men and needed their obedience to be their God. Then God would be in fact no different from an idol of race, nation, family, or whatever, and a man would feel justified either by his obedience to the idol or by the punishment of his disobedience.
