When people live with God, they live the life of Great souls, but when they live for God, everybody starts fighting to defend the only one creator God, forgetting totally the living of great religious life!!
When people start living for God, then, they start converting people of other faiths to their religion, and the desire for making their religion the only world-religion raises. All religions are now on the battlefield to make their religion that one final religion in this world!!! This is the situation that ancient sorcery system has been waiting for, and it will drive the chariots and ride the horses on the battlefield, only to make everybody fail totally, by pushing each one of them down to deep immoral ditch. This waits for all the religions. Thus, try to live with God like the Great souls, who had lived in every religion with the universal Truth, Love, and Morality as the essence of their God and religion, but cared rituals only with minimal importance.
