Free will = / = killing everyone, didn't god strap them of their free will when he killed them all?
Remember God's words to Adam and Eve in the garden? "The day you eat of it you will surely die." Even though they were walking around like they were alive, they were already dead in spirit, because they willingly, freely, ate. They removed themselves from free will when they killed themselves.
Their children were dead, even though the machinery of their bodies and minds appeared to be alive. Why? You can't get life out of something that is dead. Spiritually, they were dead already. The body and mind were made so well by god that they seemed to remain alive for centuries (in some cases) even though the spirits were dead already.
There is only one way to come back to life. That is to believe in Jesus salvation. With faith life is renewed by God. "You are gods, to whom the Word of God comes." This doesn't mean simply reading it. It means a penetration of the Spirit of the Word into the heart and soul of the reader. Such believers never die, even when their bodies are dead.
Great argument, why didn't god get rid of Adam and Eve after they ate the fruit if their spirits and the spirits of their children were already dead? Why wait until the population was big to kill everyone instead of doing it at the start? LOL
