Jesus Is God – John 1:1
The Bible teaches that Jesus is not merely
someone who is a lot like God, or someone who has a very close walk with God.
Rather, Jesus is the Most High God himself. Titus 2:13 says that as
Christians we are “looking for the blessed hope and the appearing of the glory
of our great God and Savior, Christ Jesus.” Upon seeing the resurrected
Christ, Thomas cried out, “My Lord and my God!” (John 20:28). Likewise, the
book of Hebrews gives us God the Father’s direct testimony about Christ: “But
of the Son he says, ‘Your throne, O God, is forever and ever" and the
gospel of John calls Jesus “the only begotten God” (John 1:18).

And the Word was God (kai qeo hn o logo). By exact and careful language John denied
Sabellianism by not saying o qeo hn o logo. That would mean that all of God was expressed
in o logo and the terms would be interchangeable, each having the
article. The subject is made plain by the article (o logo)
and the predicate without it (qeo) just as in John 4:24 pneuma o qeo can only mean "God is spirit,"
not "spirit is God." So in 1 John 4:16 o qeo agaph estin can only mean "God is love,"
not "love is God" as a so-called Christian scientist would confusedly
say. For the article with the predicate see Robertson, Grammar_, pp. 767f.
So in John 1:14 o Logo sarx egeneto, "the Word became flesh," not
"the flesh became Word." Luther argues that here John disposes of
Arianism also because the Logos was eternally God, fellowship of Father and
Son, what Origen called the Eternal Generation of the Son (each necessary to
the other). Thus in the Trinity we see personal fellowship on an equality.

The Word (John 1:1–3, 14) Much as our words reveal to others our hearts and
minds, so Jesus Christ is Gods Word to reveal His heart and mind to us. “He
that hath seen me hath seen the Father” (John 14:9). A word is composed of
letters, and Jesus Christ is Alpha and Omega” (Rev. 1:11), the first and last
letters of the Greek alphabet. According to Hebrews 1:1–3, Jesus Christ is God’s
last Word to mankind, for He is the climax of divine revelation.
Jesus Christ is the eternal Word (vv. 1–2). He existed in the beginning, not
because He had a beginning as a creature, but because He is eternal. He is God
and He was with God. “Before Abraham was, I am” (John 8:58).
