6Therefore my people shall know my name: therefore they shall know in that day that I am he that doth speak: behold, it is I(Isaiah 52:6).
God said that one day He would reveal a new name to the Jews and speak to them.
7If ye had known me, ye should have known my Father also: and from henceforth ye know him, and have seen him.
8Philip saith unto him, Lord, show us the Father, and it sufficeth us.
9Jesus saith unto him, Have I been so long time with you, and yet hast thou not known me, Philip? he that hath seen me hath seen the Father; and how sayest thou then, Show us the Father?
10Believest thou not that I am in the Father, and the Father in me? the words that I speak unto you I speak not of myself: but the Father that dwelleth in me, he doeth the works.
11Believe me that I am in the Father, and the Father in me: or else believe me for the very works' sake(John 14:7-11).
The only way you can see the invisible God is by Jesus,the visible relationship of God to the saints,and the Spirit is God's invisible relationship to the saints.
