At least four things are needed for the success of this divine plan:
First was the Creation of the earth as our dwelling place. Whatever the details of the creation process, we know that it was not accidental but that it was directed by God the Father and implemented by Jesus Christ—“all things were made by him; and without him was not any thing made that was made.”
Second is the condition of mortality. Adam and Eve acted for all who had chosen to participate in the Father’s great plan of happiness. Their Fall created the conditions needed for our physical birth and for mortal experience and learning outside the presence of God. With the Fall came an awareness of good and evil and the God-given power to choose. Finally, the Fall brought about physical death needed to make our time in mortality temporary so that we would not live forever in our sins.
Third is redemption from the Fall. We see the role of death in our Heavenly Father’s plan, but that plan would become void without some way to overcome death in the end, both physical and spiritual. Thus, a Redeemer, the Only Begotten Son of God, Jesus Christ, suffered and died to atone for Adam and Eve’s transgression, thereby providing resurrection and immortality for all. And since none of us will have been perfectly and consistently obedient to the gospel law, His Atonement also redeems us from our own sins on condition of repentance. With the Savior’s atoning grace providing forgiveness of sins and sanctification of the soul, we can spiritually be born again and reconciled to God. Our spiritual death—our separation from God—will end.
Fourth, and finally, is the setting for our physical birth and subsequent spiritual rebirth into the kingdom of God. For His work to succeed to “[exalt us] with himself,” God ordained that men and women should marry and give birth to children, thereby creating, in partnership with God, the physical bodies that are key to the test of mortality and essential to eternal glory with Him. He also ordained that parents should establish families and rear their children in light and truth, leading them to a hope in Christ...A family built on the marriage of a man and woman supplies the best setting for God’s plan to thrive—the setting for the birth of children, who come in purity and innocence from God, and the environment for the learning and preparation they will need for a successful mortal life and eternal life in the world to come. A critical mass of families built on such marriages is vital for societies to survive and flourish. That is why communities and nations generally have encouraged and protected marriage and the family as privileged institutions.
It has never been just about the love and happiness of adults.
