Jesus Christ serves as a vital link between God the Father and man in many ways. One of the ways to make the case for mankind being literal spirit children of God the Father is to make a connection between mankind and Jesus Christ. Then the more obvious link between Christ and God the Father helps complete an understanding of the relationship between God and man.
The scriptures speak of Jesus being the firstborn of the Father. Paul wrote:
Giving thanks unto the Father, which hath made us meet to be partakers of the inheritance of the saints of light: Who hath delivered us from the power of darkness, and hath translated us into the kingdom of his dear Son: In whom we have redemption through his blood, even the forgiveness of sins: Who is the image of the invisible God, the firstborn of every creature: (Col. 1:12-15)
The Doctrine and Covenants also teaches this:
And now, verily I say unto you, I was in the beginning with the Father, and am the Firstborn; (D&C 93:21)
Scriptures like these are used to establish Jesus Christ as being the first born spirit child of God the Father. The term firstborn is key to this connection. ‘First’ implies a sequence with Christ at the beginning. And while the mind, will, or ‘intelligence’ is eternal, the spirit body must have had a beginning in time or else being first makes little sense. The term ‘born’ is also significant as it implies the method of just such a beginning.
A scripture I use very frequently on this topic is this:
Furthermore we have had fathers of our flesh which corrected us, and we gave them reverence: shall we not much rather be in subjection unto the Father of spirits, and live? (Heb. 12:9)
This scripture draws an obvious parallel between fathers of flesh and Father of spirits, using the same word for both within the same sentence. The context is unmistakable.
Christ uses a beautiful and inclusive statement to Mary shortly after his resurrection when he says:
…Touch me not; for I am not yet ascended to my Father: but go to my brethren, and say unto them, I ascend unto my Father, and your Father; and to my God, and your God. (John 20:17)
This, along with the Lord’s Prayer, offer a very pleasing link between Jesus Christ and all mankind. The scriptures let us know that Christ is the firstborn spirit child of God the Father, and that God is also the Father of our spirits. Christ seemed to go out of his way to establish his brotherhood with us, as spirit children of the same God.
Jesus Christ as ‘Elder brother’ is an important relationship that helps establish the idea of man as the literal spirit child of God.
