As a prior post mentions, Christ explained “eternal life” as knowing Him: “And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent.” (John 17:3.)
The writers of the New Testament knew Christ. They were taught by Him or He appeared to them. Prior to His death, Christ promised He would continue to be known, because He and His Father would take up their abode with others in the future. “Judas saith unto him, not Iscariot, Lord, how is it that thou wilt manifest thyself unto us, and not unto the world? Jesus answered and said unto him, If a man love me, he will keep my words: and my Father will love him, and we will come unto him, and make our abode with him.” (John 14:22-23.) This promise was intended to be taken literally.
In addition to His followers, the antagonist (Saul) was also visited after Christ’s resurrection. Christ approached him on the road to Damascus. (See Acts 9:1-22.) Christ appeared and then took up His abode with Paul, who was later caught up to heaven and was taught “unspeakable things” of the mysteries of God. (See 2 Cor. 12:1-5.)
A modern prophet explained that Christ’s promise to “take up his abode” with men is not merely figurative or in the heart, but is indeed a personal appearance in which the believer comes to know his Lord: “John 14:23—The appearing of the Father and the Son, in that verse, is a personal appearance; and the idea that the Father and the Son dwell in a man’s heart is an old sectarian notion, and is false.” (D&C 130:3.)
Christ appeared to Joseph Smith and he testified of the appearing:
I saw a pillar of light exactly over my head, above the brightness of the sun, which descended gradually until it fell upon me. It no sooner appeared than I found myself delivered from the enemy which held me bound. When the light rested upon me I saw two Personages, whose brightness and glory defy all description, standing above me in the air. One of them spake unto me, calling me by name and said, pointing to the other—This is My Beloved Son. Hear Him!” (JS-History 1:16-17.)
In another appearance to both Joseph Smith and Sidney Rigdon, they jointly testified:
the Lord touched the eyes of our understandings and they were opened, and the glory of the Lord shone round about. And we beheld the glory of the Son, on the right hand of the Father, and received of his fulness; And saw the holy angels, and them who are sanctified before his throne, worshiping God, and the Lamb, who worship him forever and ever. And now, after the many testimonies which have been given of him, this is the testimony, last of all, which we give of him: That he lives! For we saw him, even on the right hand of God; and we heard the voice bearing record that he is the Only Begotten of the Father— That by him, and through him, and of him, the worlds are and were created, and the inhabitants thereof are begotten sons and daughters unto God. (D&C 76:19-24.)
Christianity was never intended to be controlled by pastors, ministers, priests, bishops or even apostles. Christianity was intended to be alive, with Christ directly involved with His followers. But the creeds of Historic Christianity have impeded the relationship between a God who wants to be known and religious institutions who preach He is unknowable.
The entire message of Joseph Smith can be reduced to one verse in the Bible: James 1:5: “If any of you lack wisdom, let him ask of God, that giveth to all men liberally, and upbraideth not; and it shall be given him.” Joseph believed this and asked. God answered. Christians can all do the same. “But let him ask in faith, nothing wavering. For he that wavereth is like a wave of the sea driven with the wind and tossed.” (James 1:6.)
God has the capacity to answer all prayers addressed to Him. And He will send no one away empty-handed.
Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you: For every one that asketh receiveth; and he that seeketh findeth; and to him that knocketh it shall be opened. Or what man is there of you, whom if his son ask bread, will he give him a stone? Or if he ask a fish, will he give him a serpent? If ye then, being evil, know how to give good gifts unto your children, how much more shall your Father which is in heaven give good things to them that ask him? (Matt. 7:7-11.)
