John 14:6 Jesus said to him, "I am the way, the truth, and the life. No one comes to the Father except through Me. 7 "If you had known Me, you would have known My Father also; and from now on you know Him and have seen Him." 8 Philip said to Him, "Lord, show us the Father, and it is sufficient for us." 9 Jesus said to him, "Have I been with you so long, and yet you have not known Me, Philip? He who has seen Me has seen the Father; so how can you say, 'Show us the Father'? 10 "Do you not believe that I am in the Father, and the Father in Me? The words that I speak to you I do not speak on My own authority; but the Father who dwells in Me does the works. 11 "Believe Me that I am in the Father and the Father in Me, or else believe Me for the sake of the works themselves. 12 ¶ "Most assuredly, I say to you, he who believes in Me, the works that I do he will do also; and greater works than these he will do, because I go to My Father. 13 "And whatever you ask in My name, that I will do, that the Father may be glorified in the Son. 14 "If you ask anything in My name, I will do it.

Jesus is the way to God because He is the truth from God and the life from God. He is the truth because He embodies God's supreme revelation (1:18; 5:19; 8:29).John 1:18 No one has seen God at any time. The only begotten Son, who is in the bosom of the Father, He has declared Him. He is the life because He contains and imparts divine life. Jesus is not merely One who has shown men the way; He is the way. It is His death, resurrection, and ascension that has made a way for men to spend eternity with God in heaven. He is not merely a way; He is the way. He is the one and only way that God has provided for men to obtain the forgiveness of their sins and the gift of eternal life. Lest anyone miss this point, Jesus says it again, in the plainest of words: “No one comes to the Father except through Me.” To know Jesus is to know the way to the Father, for He is the way. This was an exclusive claim to being the only way to heaven. John 10:9 "I am the door. If anyone enters by Me, he will be saved, and will go in and out and find pasture.

Ac 4:12 "Nor is there salvation in any other, for there is no other name under heaven given among men by which we must be saved."

1Ti 2:5 For there is one God and one Mediator between God and men, the Man Christ Jesus,

It is only because of Jesus Christ's work on the cross that anyone can enter heaven. Since He has come it is only through faith in the promise of God that His cross work satisfied the Father that anyone experiences regeneration John 1:12; 3:16;

1Jo 2:2 And He Himself is the propitiation for our sins, and not for ours only but also for the whole world.
