My sister just called me today to tell me she learned something new in church yesterday. She said that Jesus is the God of the Old Testament. I just read on your site that Mormons believe that Jesus was the Jehovah of the Old Testament. If Jehovah (Jesus) gave Israel the Ten Commandments, including the one that says they should worship no other gods, then why do Mormons not pray to Jesus, but to “God the Father”. Who is “God the Father” in the Old Testament? Please explain.
God the Father (Elohim) and His Son Jesus Christ (Jehovah), although two distinct personages are one in purpose, as clearly implied by the words of the Savior in John 17:20-21
Neither pray I for these alone, but for them also which shall believe on me through their word;
That they all may be one; as thou, Father, art in me, and I in thee, that they also may be one in us: that the world may believe that thou hast sent me.
God the Father, as the name implies, is the father of the spirits of all humanity. Our Lord and Savior, Jesus Christ, was His first born Son in the spirit world, who became the Redeemer of all mankind. It was He–Jesus Christ of the New Testament and Jehovah of the Old Testament–who commanded us to pray to the Father in His name—
And whatsoever ye shall ask in my name, that will I do, that the Father may be glorified in the Son.
If ye shall ask any thing in my name, I will do it (John 14:13-14).
