God Has Provided a Way for Both Mercy and Justice to Be Served
Alma 42:15
15 And now, the plan of mercy could not be brought about except an atonement should be made; therefore God himself atoneth for the sins of the world, to bring about the plan of mercy, to appease the demands of justice, that God might be a perfect, just God, and a merciful God also.
President John Taylor wrote:
“The Savior thus becomes master of the situation—the debt is paid, the redemption made, the covenant fulfilled, justice satisfied, the will of God done, and all power is now given into the hands of the Son of God—the power of the resurrection, the power of the redemption, the power of salvation, the power to enact laws for the carrying out and accomplishment of this design. Hence life and immortality are brought to light, the gospel is introduced, and He becomes the author of eternal life and exaltation, He is the Redeemer, the Resurrector, the Savior of man and the world. . . . Is justice dishonored? No; it is satisfied, the debt is paid. Is righteousness departed from? No; this is a righteous act. All requirements are met. Is judgment violated? No; its demands are fulfilled.”
