God expects us to be who we are, but he also expects us to repent when we sin. He didn't create us waiting to say, "There! I got you! Now you'll go to hell." Far from it.
As for your "scientific improbability" of God, there are many scintific PROBABILITIES of God. There have been instances of proving the existance of God, not disproving it. Science can't explain everything, but I believe the more we learn about science, the more we learn about God. We can explore God's vast and amazing creation with science, yet we ridiculous humans attempt to disprove him. Do you think everything that is here happened merely by chance? Chance! Ha! This could not all be up to chance. If evolution is real, as science states, how come we can't find anything remotely close to Earth out there? How come nothing out there resembles Earth's conditions? Could it be that a loving creator put us here for a reason?
