After you pass Joseph you come to the Father through His Son, Jesus Christ. Mormon doctrine refers to Christ as being our advocate and mediator with the Father.
4 I am the first and the last; I am he who liveth, I am he who was slain; I am your advocate with the Father.
5 Behold, your sins are forgiven you; you are clean before me; therefore, lift up your heads and rejoice. (Doctrine and Covenants, Section 110)
26 And the Messiah cometh in the fulness of time, that he may redeem the children of men from the fall. And because that they are redeemed from the fall they have become free forever, knowing good from evil; to act for themselves and not to be acted upon, save it be by the punishment of the law at the great and last day, according to the commandments which God hath given.
27 Wherefore, men are free according to the flesh; and all things are given them which are expedient unto man. And they are free to choose liberty and eternal life, through the great Mediator of all men, or to choose captivity and death, according to the captivity and power of the devil; for he seeketh that all men might be miserable like unto himself. (Book of Mormon, 2 Nephi, Chapter 2)
