Isn’t the following a great quote by Elder Holland? It comes from a BYU devotional that can be found here.
You can change anything you want to change, and you can do it very fast. That’s another satanic suckerpunch—that it takes years and years and eons of eternity to repent. It takes exactly as long to repent as it takes you to say, “I’ll change”—and mean it. Of course there will be problems to work out and restitutions to make. You may well spend—indeed you had better spend—the rest of your life proving your repentance by its permanence. But change, growth, renewal, and repentance can come for you as instantaneously as for Alma and the sons of Mosiah. Even if you have serious amends to make, it is not likely that you would qualify for the term, “the vilest of sinners,” which is the phrase Mormon uses in describing these young men. Yet as Alma recounts his own experience in the thirty-sixth chapter of the book that bears his name, his repentance appears to have been as instantaneous as it was stunning.
This talk also includes a good Pioneer Day story and another good quote –
In the gospel of Jesus Christ you have help from both sides of the veil, and you must never forget that. When disappointment and discouragement strike—and they will—you remember and never forget that if our eyes could be opened we would see horses and chariots of fire as far as the eye can see riding at reckless speed to come to our protection. They will always be there, these armies of heaven, in defense of Abraham’s seed.
