Let not your heart be troubled: believe in God, believe also in me. In my Father's house are many mansions; if it were not so, I would have told you; for I go to prepare a place for you. And if I go and prepare a place for you, I come again, and will receive you unto myself; that where I am, there ye may be also. And whither I go, ye know the way. Thomas saith unto him, Lord, we know not whither thou goest; how know we the way? Jesus saith unto him, I am the way, and the truth, and the life: no one cometh unto the Father, but by me.
Jesus told him, "I am the way, the truth, and the life. No one can come to the Father except through me." (John 14:6)
