As members of The Church of Jesus Christ of Latter Day Saints (or the Mormon Church as it is commonly known,) we believe in the Plan of Salvation, or the “the great plan of happiness” as Alma called it in the Book of Mormon (Alma 42:8.)
The gospel teaches us that we are all the spirit children of heavenly parents. Our purpose in coming to earth is to work toward eternal life. We are here to choose for ourselves the way we would go, so that our eventual homecoming will be all the more sweet.
Mormon beliefs teach that there was a great council in heaven where the spirit children of God were taught His eternal plan, or that great plan of happiness. Without a physical body we had progressed as far as we could. To realize a fullness of joy, we had to learn to choose for ourselves, to prove that we would keep the commandments of God in circumstances where we had no memory of our premortal life.
Here on earth, our bodies would be subject to all manner of infirmities, even death. We would be allowed to be tempted by Satan. Our Heavenly Father’s plan provided a Savior for us whose atonement would redeem us from death and pay the price for sins so that we could be forgiven and made clean once more if we would repent.
When we understand the Plan of Salvation, we can feel peace in our understanding of the purpose of God’s commandments and we can obtain happiness in following the path the Plan lays out for us. I encourage you to follow His Plan in faith. If you know what is right and strive to choose accordingly, repent of your missteps when they happen, you can partake in God’s promised mercy and you will be happy.
