''When Jesus died on the cross, He took the punishment for all sins... for all mistakes... to correct the whole thing. Since all sins have been paid for, there is nothing owing.'' First of all, isn't Jesus, God? - Yes, Jesus is God. And why would he ''sacrifice'' himself for us and can you even call it a sacrifice if he revived later on? - He didn't revive. He died. He took our place, paid our debt, because He and His Father loved us. Why does God need anyone to sacrifice himself to save us and why would that save us? - God is self-sufficient. He doesn't need anything. Because Jesus is God, He is great enough to be able to save all of us with His death in place of ours.

''If a person can't make payments on his bank loan, and a different person pays off the loan for him, does he still owe it? No'' Nice analogy buddy, are we supposed to kill ourselves for god at all times and that's why jesus sacrificed himself or how does it work. - No, we are not supposed to kill ourselves. But we are allowed if we are sacrificing ourselves for the lives of others out of love for them. See previous paragraph for the reason why Jesus sacrificed Himself.

Wouldn't an all knowing god already know all this, why allow it in the first place if the whole thing is going to be a mess - To give you freedom to be able to make choices, be they right ones or wrong ones. and he will kill everyone with the flood? - Since He didn't kill everyone with a flood, the question is not applicable. If he was going to kill everyone why bother creating humans before that? - Since He didn't kill everyone, the question is not applicable.
