so you mean, what happens if we Reject what God wants for us(not just, not knowing)?
or do you mean, what happens if we, unknowingly do something wrong?
to either question... All have sinned and God will take us back if we repeant of what we've done. I beleive that God looks at the heart of a person, and if they are striving for the mark, to be perfect in spirit, then they'll enter in to heaven when they die. God knows that in flesh, we are imperfect but through him we can be made perfect in spirit. I think I may have not answered your question though, could you please clarrify what you were saying?
