Gender Existed Premortally | Richard G. Scott

The scriptures record, “And I, God, created man … ; male and female created I them.” This was done spiritually in your premortal existence when you lived in the presence of your Father in Heaven. Your gender existed before you came to earth. You elected to have this earth experience as part of His plan for you. The prophets call it “the plan of mercy,” the “eternal plan of deliverance,” “the plan of salvation,” and, yes, “the great plan of happiness.” You were taught this plan before you came to earth and there rejoiced in the privilege of participating in it.
