No child of God sins to that degree as to make himself incapable of forgiveness

If you have sinned, do not lie down without repentance; for the want of repentance after one has sinned makes the heart yet harder and harder

God needs loving, accepting, and compassionate people—not accepting of sin, but accepting God’s forgiveness of sin for all who repent. 

We have a strange illusion that mere time cancels sin. I have heard others, and I have heard myself, recounting cruelties and falsehoods committed in boyhood as if they were no concern of the present speaker's, and even with laughter. But mere time does nothing either to the fact or to the guilt of a sin. The guilt is washed out not by time but by repentance and the blood of Christ: if we have repented these early sins we should remember the price of our forgiveness and be humble.

Repentance for past crimes is just and easy; but sin-no-more's a task too hard for mortals

Nothing can hurt you except sin; nothing can grieve me except sin; nothing can defeat you except sin. Therefore, be on your guard, my Mansoul.
