The atonement of Jesus Christ is infinite in the sense that it conquers the most universal reality in mortal existence—death. The earth and every plant and animal upon it—all forms of life—are subject to death through the Fall. The light of the Atonement must shine upon all who were previously shadowed by the effects of the Fall. An infinite atonement must bring life to all that is subject to death.
“This Corruption Could Not Put on Incorruption”
If there were no atonement and thus no infinite power by which to bring about the resurrection from the dead, then man would be without the hope of Job: “In my flesh shall I see God” (Job 19:26). “We shall all be changed,” Paul assured us, “in a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed. For this corruptible [body] must put on incorruption, and this mortal [body] must put on immortality.... Then shall be brought to pass the saying that is written [in Isaiah 25:8; Hosea 13:14], Death is swallowed up in victory.” (1 Corinthians 15:51-54.)
