Yes, Jesus is fully God.
In the book of John and Genesis it starts with the same 3 words. In the book of John it talks about how Jesus is the Word and the Word was with God and it also says that the Word is God. Word in Greek means Logos.
I think what this says about him and his ministry is that Jesus is the Word of God and we should follow him so we can have eternal life. God Bless ❤️
