And where I go you know, and the way you know. Thomas said to Him, “Lord, we do not know where You are going, and how can we know the way?” Jesus said to him, “I am the way, the truth, and the life. No one comes to the Father except through Me.” (John 14:4-6)
Jesus was about to die, be resurrected from the dead and ascend to the Father in order to accomplish human redemption (Heb. 7:25; 9:24-28). By doing so, Jesus makes the way to heaven possible. You can only come to the Father “through” Jesus. You will only go to heaven on His terms, not your own. He is “the way”, the only way that leads to the Father. His truth is the way that leads to eternal life. Since Jesus is “the truth”, you cannot live in error and go to heaven. It will not do to define Jesus on your terms. Because He is “the truth”, you must conform yourself to Him. Eternal life is only through Jesus; He is “the life”. Come to the Father through Him and be saved.
