One of my favorite scriptures is Mosiah 27:29.
"My soul hath been redeemed from the gall of bitterness and bonds of iniquity. I was in the darkest abyss; but now I behold the marvelous light of God. My soul was racked with eternal torment; but I am snatched, and my soul is pained no more."
I love the contrast of the darkness and the light in this verse. This verse reminds me that no matter how far off the path I think I've fallen, I can always be forgiven and return to where I need to be. Through the gift of repentance through the atonement of Jesus Christ, I can find peace and love again.
