John 1:4
4. In Him was life—essentially and originally, as the previous verses show to be the meaning. Thus He is the Living Word, or, as He is called in 1Jo 1:1, 2, "the Word of Life."
the life . . . the light of men—All that in men which is true light—knowledge, integrity, intelligent, willing subjection to God, love to Him and to their fellow creatures, wisdom, purity, holy joy, rational happiness—all this "light of men" has its fountain in the essential original "life" of "the Word" (1Jo 1:5-7; Ps 36:9).John 11:25
25. Jesus said, I am the resurrection and the life—"The whole power to restore, impart, and maintain life, resides in Me." (See on Joh 1:4; Joh 5:21). What higher claim to supreme divinity than this grand saying can be conceived?
he that believeth in me, though . . . dead . . . shall he live—that is, The believer's death shall be swallowed up in life, and his life shall never sink into death. As death comes by sin, it is His to dissolve it; and as life flows through His righteousness, it is His to communicate and eternally maintain it (Ro 5:21). The temporary separation of soul and body is here regarded as not even interrupting, much less impairing, the new and everlasting life imparted by Jesus to His believing people. Believest thou this?—Canst thou take this in?John 14:6
4-7. whither I go ye know . . . Thomas saith, Lord, we know not whither thou guest . . . Jesus saith, I am the way, &c.—By saying this, He meant rather to draw out their inquiries and reply to them. Christ is "THE WAY" to the Father—"no man cometh unto the Father but by Me"; He is "THE TRUTH" of all we find in the Father when we get to Him, "For in Him dwelleth all the fulness of the Godhead bodily" (Col 2:9), and He is all "THE LIFE" that shall ever flow to us and bless us from the Godhead thus approached and thus manifested in Him—"this is the true God and eternal life" (1Jo 5:20).
