Enos 1:5-6

And there came a voice unto me, saying: Enos, thy sins are forgiven thee, and thou shalt be blessed. And I, Enos, knew that God acould not lie; wherefore, my guilt was swept away. (link)

I know that when we repent of our sins, God will forgive us and take our guilt away. I am so thankful to have felt that assurance through the Holy Ghost when I repent. Repentance is such a blessing.
