"I frankly forgave them." This was Nephi's response to his brothers when, after they tied him up with the intent on KILLING him and leaving him for the WILD BEASTS TO DEVOUR, he gets loose, and they come at him again just be be persuaded by a sister, mother and brother from ANOTHER family to spare Nephi's life, they then get down on their knees to beg forgiveness. It doesn't say that he lectured them and held a grudge for a week or two, or a month, or even a minute. He frankly forgave them.
How many times do we hold a grudge for silly things that don't matter as much as losing our lives would? Are we, right now, holding on to pain and anger for trivial matters? Can't we just "frankly forgive?" I dare you, and myself to follow this example.
