How much do children know before their mortal birth about God and the plan of salvation?
Every person born into the world comes from the presence of God. We all saw him in that eternal world. We heard his voice. He taught us his laws. We learned about Christ and chose to follow him when he was chosen to be our Savior and Redeemer. We understood and knew the gospel plan and shouted for joy at the privilege of getting our mortal bodies as part of that great plan of salvation. Returning pure and spotless to their Maker, children—who in reality are adults—will again have that gospel knowledge which once was theirs.
