Fact: All have sinned and fall short of the glory of God.
Fact: All sins are equally damnable in the sight of God, but not all sins are equal in damage caused to ourselves and others.
Fact: Since all sins have been paid for by our Lord Jesus Christ in his death, Christians should forgive an offending brother from the heart.
Fact: Forgiveness of sins does not always erase the effects of sin. One may sincerely forgive an offending brother (or sister) of his or her sins, but this does not mean that things will necessarily go back to normal. Depending on the magnitude of the sin, and the damage caused to others, it may indeed be impossible for things to go back to normal (i.e. the way it was before).
I say this because I have found over the years in my dealings with church members that people often do not seem to understand that sin, though forgiven, has consequences. The consequences may be larger or smaller but there are consequences nonetheless. Adam and Eve, though fully forgiven by God for their rebellion, were nonetheless banished from the Garden. Now there is pain in child birth for the woman and work is irksome for man. King David, though absolved by Nathan the Prophet, lost his firstborn son. A public criminal who repents and is forgiven may still have to go to jail. A man who is unfaithful to his wife, but repents and ceases his infidelity may indeed reconcile with his wife but the relationship will more than likely be strained and certain limits may be placed on one’s freedom afterward.
Perhaps more people would avoid sinning, if they only thought more about the effects their sins would have on others, and the potential consequences of their actions. But alas, the flesh is weak, and the devil “prowls around like a roaring lion, seeking someone to devour.” Jesus alone is our refuge from sin AND its effects.
