Jesus and his sacrifice is Satan’s test of man’s morality.

Where do you get this from? What I mean by that is where does it say that if you do not accept that Jesus died for our sins means that you are going to Hell? From a logical standpoint, if Jesus in fact did die for our sins it does not make sense that unbelief in that act would condemn a person to hell - assuming you are saying unbelief is sin and that any sin puts a person in Hell. If unbelief is sin, is that sin not also not accounted for by the sacrifice of Jesus?
