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 14:6, NKJV.
I’ve heard many people object that Christians have no right to say that Jesus is the only way to God. I’ve also heard people say that Jesus never said He was God (not true, He said it many times in a number of different contexts). Seems to me, if people would recognize that He said He was God, then they would realize that, of course He was the only way to God, because He was God. He was the only way to reach Himself.
In addition, Jesus was the only figure representing a religion who called Himself God. Mohammed said he was Allah/God’s messenger, Buddhism has no gods, and Hinduism has 33 million gods.
“I and My Father are one.” ~ John 10:30, NKJV.
Philip said to Him, “Lord, show us the Father, and it is enough for us.” Jesus said to him, “Have I been with you so long, and you still do not know Me, Philip? Whoever has seen Me has seen the Father. How can you say ‘Show us the Father’?” ~ John 14:8-9, ESV.
It would be true that Jesus couldn’t say that He’s the only way to access God if He weren’t God but He is. He said He was God on many different occasions, as illustrated by the two instances above.
Additionally, when He was on the cross, one of the last things Jesus said was, “It is finished.” ~ John 19:30, NKJV. Then He died, after which the veil in the temple that separated the Holy Place from the Most Holy Place was torn in two from top to bottom. This was no mean feat, because the veil was reported to be sixty feet high and fifteen feet wide, and four inches thick. (some sources say it was thirty feet high and fifteen feet wide). Plus it was torn from top to bottom, sixty feet in the air, something no human being could have accomplished.
The veil was significant because it separated the Holy Place from the Most Holy Place in the temple, and originally in the tabernacle, and God was thought to have resided in the Most Holy Place. So if the veil separating the two was gone, then the wall closing off humanity from relationship with God was now removed, giving man access to God for the very first time since Adam’s sin way back in the beginning.
The upshot of all this is that if Jesus said He’s the way to reach God, and He speaks only the truth, then He must be the way to reach God because He was the only human to ever walk the earth who lived a perfect, sinless life. So He’s the only one who could be a bridge between us and a Holy God.
And He is exactly that!
