Elder Jeffrey R. Holland noted the chilling line in Mormon’s account that time had run out for saving his people: “It is at this moment in Nephite history—just under 950 years since it had begun and just over 300 years since they had been visited by the Son of God himself—that Mormon realized the story was finished. In perhaps the most chilling line he ever wrote, Mormon asserted simply, ‘I saw that the day of grace was passed with them, both temporally and spiritually.’ His people had learned that most fateful of all lessons—that the Spirit of God will not always strive with man; that it is possible, collectively as well as individually, to have time run out. The day of repentance can pass, and it had passed for the Nephites. Their numbers were being ‘hewn down in open rebellion against their God,’ and in a metaphor almost too vivid in its moral commentary, they were being ‘heaped up as dung upon the face of the land’” (Christ and the New Covenant, 319).
President Spencer W. Kimball (1895–1985) described how we today might also remove ourselves from the cleansing grace of repentance: “It is true that the great principle of repentance is always available, but for the wicked and rebellious there are serious reservations to this statement. For instance, sin is intensely habit-forming and sometimes moves men to the tragic point of no return. … As the transgressor moves deeper and deeper in his sin, and the error is entrenched more deeply and the will to change is weakened, it becomes increasingly near-hopeless, and he skids down and down until either he does not want to climb back or he has lost the power to do so” (The Miracle of Forgiveness [1969], 117).
