Just read what is written…
King James Bible
In the beginning was the Word, and the Word was with God, and the Word was God
14 And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.
God is the Word. The Word is God. And God (word) became flesh (Jesus)
But it doesn’t get much easier than this.
God=Word — Word=Flesh — Flesh= Jesus — Jesus=God God=Word Word=Flesh Flesh=Jesus Jesus=God
