what your refering to is Existentialism. by saying there is no God is not going to fix any problems the same way saying there is no gravity is gonna make u fly. God never said to place all blame on the devil. we do have decisions to make in this life and many many people make the wrong ones. I was once to a point where i cursed God and felt like was in the lowest of the world. Not too long after that I came to know Jesus and never looked back. Today I'm at the highest point of my life and still climbing. God can do amazing things in your life if you just give him a chance.
Yes revalation is horrible, but it is going to happen. and trust me you dont want to be here for that. so why not live life right now (even if you have to suffer a bit) to spend eternity in zion
