Thomas saith unto him, “Lord, we know not whither Thou goest; and how can we know the way?”  Jesus saith unto him,
“I am the way, the truth, and the life: no man cometh unto the Father, but by Me.  If ye had known Me, ye should have known My Father also: and from henceforth ye know Him, and have seen Him.”
Philip saith unto Him, “Lord, shew us the Father, and it sufficeth us.” Jesus 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, ‘Shew us the Father?’ Believest 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. Believe me that I am in the Father, and the Father in Me: or else believe Me for the very works’ sake.”
John 14:5-11
