Well, any sin separates us from God. :roll: Punishment for one sin could be more severe than another, but that's simply a matter of atonement for the sin. When you have received the gift of salvation, all your sins have been paid for, thus the punishment is endurable and helps us grow, because Christ's propitiation is complete. If you haven't received salvation, your sins are not atoned for and you are subject to punishment. But for every sin there is an equal and opposite reaction that God set up. It doesn't have to do with severity really. If I steal, something will be taken from me, be it my honor or God's blessings for that time. If I murder, the equal and opposite reaction will fall upon me, unless, for some reason, a longer but more useful reaction is devised by God, like life in prison to reach out to other lost souls.
