John 14:5-7

5 Thomas saith unto him, Lord, we know not whither thou goest; and how can we know the way? 

6 Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me. 

7 If ye had known me, ye should have known my Father also: and from henceforth ye know him, and have seen him.
