Taking our mind off of God's will for one minute is sin. Whether it is to take an apple off of someone else's tree or to murder someone, the result is the same - enmity with God. Yet while we were enemies with God, He provided the perfect blood sacrifice to pay for our sins. That is the only method that He accepts to reconcile us or to put us in a state of perfection. For without the shedding of blood there is no forgiveness of sin.
