I Don't Believe In God

God is supposed to be this spiritual great man. But what kind of “god” allows his people as “he calls us” to suffer. Innocent babies/kids and people all together are dying everyday. What kind of god allows kids and people to be born with cancer and other serious problems? They say “it’s the devil working” but the also say “god is stronger than the devil”. So if that’s true he would have the power to stop it but he doesn’t so this “great god” that many worship doesn’t exist. Also it doesn’t seem as if he really wants us to love who we want, as long as we are happy and no hurting anyone. We all have to be straight and boring thats his agenda.
