The plan of salvation is also referred to as the plan of happiness, the plan of redemption, or the plan of mercy. According to LDS teachings, Heavenly Father prepared this plan in the pre-mortal existence. He wants all of his spirit children to fully exercise their divine potential and become like Him. Those who exercised their agency wisely and made the decision to follow Heavenly Father and Jesus Christ in the pre-mortal world, were allowed to come to earth to be tested and to experience mortal life in order to eternally progress toward Exaltation.
Creation, Adam’s Fall, Christ’s Atonement, and all of the commands and the laws of the LDS gospel are part of this plan. During this mortal life or “time of learning” a person can begin to prove themselves and “prepare to be worthy of eternal life.” After death, a person’s spirit enters the spirit world to continue their eternal progression and await the resurrection of their body. On Judgment Day, Mormonism believes that Heavenly Father will judge a person’s worthiness and award a kingdom of glory. “Because of this plan, we can be perfected through the Atonement, receive a fulness of joy, and live forever in the presence of God. Our family relationships can last throughout the eternities.” (True to the Faith, p. 115)
Biblical Christianity teaches:
God established the plan of salvation for the ultimate purpose of receiving glory. He receives glory by doing everything to rescue us from spiritual death. God is even the one who elects us to receive faith so again; he can receive the glory (Eph. 1:3-14). By His perfect life and death on the cross, Jesus Christ substituted Himself in place of all people and paid the penalty of sin. The Holy Spirit is the one who creates faith so each person can receive the full benefits of Christ’s victory over death and sin.
