Repentance

Some wonderful repentance scriptures:

Mosiah 26:30 Yea, and as often as my people repent will I forgive them their trespasses against me.   Alma 36:30 Keep the commandments and prosper in the land.
D&C 1:32 Nevertheless, he that repents and does the commandments of the Lord shall be forgiven.
D&C 19:16 For behold I, God, have suffered these things for all, that they might not suffer if they would repent.
D&C 58:42-43 Behold, he who has repented of his sins, the same is forgiven, and I, the Lord, remember them no more.  43: By this ye may know if a man repenteth of his sins- behold, he will confess them and forsaken them.
Isaiah 1:18 ..thou your sins be as scarlet, they shall be as white as snow; though they be red like crimson, they shall be as wool.

Quotes:
"What relief! What comfort! What joy! Those laden with transgressions and sorrows and sin may be forgiven and cleansed and purified if they will return to their Lord, learn of him, and keep his commandments."
~Spencer W. Kimball

"Repent: Perhaps the most hopeful and encouraging word in the Christian vocabulary."
~Jeffery R. Holland

“Men cannot forgive their own sins; they cannot cleanse themselves from the consequences of their sins. Men can stop sinning and can do right in the future, and so far [as] their acts are acceptable before the Lord [become] worthy of consideration. But who shall repair the wrongs they have done to themselves and to others, which it seems impossible for them to repair themselves? By the atonement of Jesus Christ the sins of the repentant shall be washed away; though they be crimson they shall be made white as wool [see Isaiah 1:18]. This is the promise given to you.”⁸
-Joseph F. Smith
