Why did Adam have to sin to be God’s companion? Here is why: He always would have had the potential to sin no matter what. He was a free willed creature. Until he did, he could not have felt remorse, and repentance could not have come to him. If repentance did not come, God could not enter and remove sin, and the potential for it ultimately.
If we don’t know repentance, we cannot be saved. God shows us our sin and the sin of others to prove Him right. This brings repentance which opens a door so Jesus can enter and save.
Jesus as man, is the very image of who He is forming us to be. He is man but perfect and without sin. This is why He is called the Last Adam. He is Adam perfected, but infinitely more than that. Jesus Christ is God and we will never be God (Mormons believe this) so this is where the pattern ends. But don’t miss the pattern that is there.
Adam is unfit. Jesus is fit and makes us into His image which also makes us fit.
Jesus is a pictur eof what His own death accomplished for and in us who believe!!!
