We lived with our Father in Heaven before we came to this Earth as His spirit sons and daughters. While there, life was similar to what we experience here: We had friendships; we learned; we progressed, and, although we cannot remember, we developed a very personal relationship with our Heavenly Father. In fact, President Ezra Taft Benson said, "Nothing is going to startle us more when we pass through the veil to the other side than to realize how well we know our Father and how familiar His face is to us" (Ensign, Dec. 1988).
Our proximity to our Heavenly Father also taught us that we were not like Him. He possessed a perfect, immortal, physical body (D&C 130:22), but we were spirits. He had a fulness of joy and glory that we did not. And He was perfect in every way, unlike us.
But as our children have the capacity to become like us, Heavenly Father knew that we had the capacity to become like Him: perfect. And He wanted us to receive the fulness of joy that He had. So Father called a council and outlined a Plan, the Plan of Salvation, through which we could become like Him. We would come to Earth for a body and to be given agency—the power to choose—whereby we would be tested if we would choose to follow God (see Abraham 3:24-26).
The power to choose for ourselves was central to this Plan. We could not become like God at once. We would need to learn from our choices to be obedient (Hebrews 5:8). Only by obeying could we progress until we became who our Father knew we could be. Without agency, no growth or progress would be possible.
Heavenly Father also told us of obstacles that would impede our progress. Although He would create a paradisiacal Earth free of sickness, suffering, sin, and death, He taught that its first inhabitants would be given a choice to either remain in paradise or pass through mortality, and if they chose mortality, mankind would be lost unless He sent a Savior, "[His] Beloved and Chosen from the beginning" (Moses 4:2), Jehovah, who would be known in the flesh as Jesus Christ. Furthermore, because we would have the power to choose, at times we would choose to sin. Our sins would also cut us off forever from the presence of our Heavenly Father. And without Jesus, we had no hope to overcome them.
Our Heavenly Father’s Plan hinged on the future sacrifice of Jesus Christ which would overcome death and sin. Father testified that "there [would] be no other name given nor any other way nor means whereby salvation [could] come unto [us], only in and through the name of Christ, . . ." (see Mosiah 3:17).
Heavenly Father gave each of us the choice to accept His plan for us. And to accept the Plan of Salvation required faith in our Father’s promises and in the ability of Jehovah, Jesus Christ, to effect the Atonement.
Lucifer, one who was in authority among the hosts of heaven (D&C 76:25), offered a variation to the Plan: He would take away our agency to prevent us from sinning so that none of us would be cut off. But he wasn’t interested in helping us to progress until we became like God with a fulness of joy. In fact, the only one he cared about was himself (see Moses 4:1-3). Lucifer’s plan enticed some to follow him even though it would not allow us to become like our Heavenly Father.
And war erupted, polarizing the hosts of heaven.
The war that ensued wasn’t fought with sword and shield but with words. And even though Heavenly Father had gathered us together in the Great Pre-mortal Council to present the Plan of Salvation, I do not believe that it was first time that we had heard it; nor do I believe that it was a surprise that He presented His Firstborn, Jehovah, to be our Savior. I am certain that there were those among us who were already exercising great faith in Jesus Christ and who took every opportunity to learn the exalting doctrines of the Plan of Salvation, among whom were you and I. And when we heard Lucifer attack God’s plan and His Anointed, we stood and testified that Jehovah would do the Father’s will as He had promised. We were victorious, and Revelation 12:10-11 teaches that "[we] overcame [Lucifer and his legions] by the blood of the Lamb, and by the word of [our] testimony [of the Atonement of Jesus Christ]. . . ."
Many feel that those who chose to follow Lucifer did so because they doubted their ability to follow the Plan to become like our Heavenly Father. Certainly, Lucifer must have cited our weakness to discourage us, but I do not believe that it was his most potent weapon. We need to remember that without the Atonement, the "corruption [of mortality brought on by the future fall] could not put on incorruption . . . [and our] flesh must [lie] down to rot and to crumble to its mother earth, to rise no more. . . . And we [would] become devils, . . . to be shut out from the presence of our God, . . . in misery, . . ." (2 Nephi 9:7-9).
If the Savior failed, all would be lost, and Lucifer did everything he could to destroy faith in Jesus Christ. Ultimately, those who had faith in Christ followed God’s Plan, and those who did not were cast out of heaven (Isaiah 14:12; Revelation 12:7-10).
I know that we lived with our Father in Heaven before we came to Earth, and I know that we accepted His Plan for us, including the appointment of our Savior, Jesus Christ.
That is why we are here.
