John 14:6, according to the KJV translation, contains the following words of Jesus:
I am the way, the truth, and the life: no man cometh unto the Father, but by me.
Here are some interesting passages to consider in relation to Jesus's words:
The Holy [Spirit] this signifying, that the way into the holiest of all was not yet made manifest, while as the first tabernacle was yet standing…. Having therefore, brethren, boldness to enter into the holiest by the blood of Jesus, By a new and living way, which he hath consecrated for us, through the veil, that is to say, his flesh; And having an high priest over the house of God; Let us draw near with a true heart in full assurance of faith…. (Heb 9:8, 10:19–22) [Note: Read Hebrews 9 and 10 highlighting Heb 9:1–3, 6–9, 11–14, 24, and 10:19–22.]
Having the understanding darkened, being alienated from the life of God through the ignorance that is in them, because of the blindness of their heart…. But ye have not so learned Christ; If so be that ye have heard him, and have been taught by him, as the truth is in Jesus: That ye put off concerning the former conversation, the old man, which is corrupt according to the deceitful lusts; And be renewed in the spirit of your mind; And that ye put on the new man, which after God is created in righteousness and true holiness. (Eph 4:18, 20–24)
That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked upon, and our hands have handled, of the Word of life; (For the life was manifested, and we have seen it, and bear witness, and show unto you that eternal life, which was with the Father, and was manifested unto us;) That which we have seen and heard declare we unto you, that ye also may have fellowship with us: and truly our fellowship is with the Father, and with his Son Jesus Christ. (1 John 1:1–3)
Those passages provide a fuller description of what it means for Christ to be the way, the truth, and the life. Christ paved the way to God when he died on the cross for our sins, so that we are able to approach God as only the high priest was able to under the old covenant. Christ corrects our vision, enabling us to see the truth, to recognize the corrupt condition of the old self that was driven by deceitful desires and to constantly renew our mind, keeping us focused on the new self we are meant to be. Christ embodied life and only through him and his life can we live in fellowship with God.
