In The Miracle of Forgiveness, Elder Spencer W. Kimball wrote of the blotting out of sins:
"The Prophet Joseph Smith expressed his assurance that sins could be blotted out: O Jehovah, have mercy upon this people, and as all men sin forgive the transgressions of thy people, and let them be blotted out forever.' (D&C 109:34.) The thought of blotting out of sins during the process of forgiveness was also expressed by the Lord when He said:I, even I, am he that blotteth out thy transgressions for mine own sake, and will not remember thy sins.' (Isa. 43:25.)" `Great are the words of Isaiah,' said the Savior (3 Ne. 23:1), and that prophet's words rise to the sublime in the well-known passage wherein he made a promise of forgiveness to all who will repent:
" `Seek ye the Lord . . . call ye upon him while he is near:
" `Let the wicked forsake his way, and the unrighteous man his thoughts: and let him return unto the Lord, . . . for he will abundantly pardon.' (Isa. 55:6-7.)
"What a glorious promise of forgiveness the Lord made through the great Isaiah! Mercy and pardon! What more could men want or hope for!"
