Some "Christians" haven't really followed it some have. This is Christianity, though.
1 John 3:18
... let us not love in word or talk but in deed and in truth.
In the Jewish Bible some are said to saw God's manifestations in the world (see "theophany"). The unique ("monogenes") Son of God or "Logos" is the only one who is said to be with God before the creation of the world and the only one sent directly from God into the world. He knows God (the Father) differently (more intimately) ...
John 3
31 He who comes from above is above all. He who is of the earth belongs to the earth and speaks in an earthly way. He who comes from heaven is above all.
32 He bears witness to what he has seen and heard, yet no one receives his testimony.
33 Whoever receives his testimony sets his seal to this, that God is true.
34 For he whom God has sent utters the words of God, for he gives the Spirit without measure.
35 The Father loves the Son and has given all things into his hand.
John 7
28...He who sent me is true, and him you do not know.
29 I know him, for I come from him, and he sent me.
John 17
5 And now, Father, glorify me in your own presence with the glory that I had with you before the world existed.
6 "I have manifested your name to the people whom you gave me out of the world. Yours they were, and you gave them to me, and they have kept your word.
7 Now they know that everything that you have given me is from you.
8 For I have given them the words that you gave me, and they have received them and have come to know in truth that I came from you; and they have believed that you sent me.
24 ... you loved me before the foundation of the world.
25 O righteous Father, even though the world does not know you, I know you, and these know that you have sent me.
26 I made known to them your name, and I will continue to make it known, that the love with which you have loved me may be in them, and I in them.
