No man has seen God at any time; the only-begotten god who is in the bosom position with the Father is the one that has explained him.—John 1:18.
Jesus was especially qualified to reveal his Father. Why? Because before all other forms of life were created, the spirit creature who later became the man Jesus already existed in heaven as “the only-begotten Son of God.” (John 1:14; 3:18) What a unique position! While no other creature existed, the Son basked in the warmth of his Father’s attention and learned about Him and His qualities. The Father and Son must have communicated extensively and developed deep affection for each other over aeons of time. (John 5:20; 14:31) What a wealth of insight into his Father’s personality the Son must have gained! (Col. 1:15-17) The Father designated the Son to be His spokesman, “The Word of God.” (Rev. 19:13) Therefore, Jesus was in a unique position to reveal the Father to others.
