How do you know this? (Let's watch the circular reasoning unfold)
I took a poll, out of 2.65 billion Christians about 2.55 billion agreed. Oops, that may be circular reasoning ... because it goes all the way around the globe - lol. No, really, that is not the reason, although it is a good one. Wouldn't the Holy Spirit pass on truth about the nature of the Son of God to the majority, rather than just 4 % of us? I mean it is a huge part of who Jesus is.
There are so many reasons that He is God. The Book of John presents Jesus deity. A list of scriptures in it describe Him as being the exact radiance and fullness of God, the Creator and source of life itself. You would have to deny or distort them or as some have suggested, if one does not really have the Holy Spirit to give you discernment, you wont grasp scripture in any depth.
Even common sense can figure that if Jesus wasn't God, why put our faith in Him, why is the whole Bible all about Him? Wouldn't the focus be on our Father? And how could anyone, unless He is God, take away the sins of the world? Omniscience, omnipresence and omnipotence is required to do that. Having all authority in heaven and earth sure sounds like the All Mighty God to me.
Why would Jesus say, I am the Bread of Life or I am the Truth or I am the Light if He was not God. He would rather point only to our Father. Not to say that He didnt. We pray to the Father, but also are baptized in Jesus name and pray in His name.
The Bible would be written quite differently. It would say our Father is the light, the way, the bread, the truth, etc., etc. - follow Him, believe in Him. We would not be in Christ, the Bible would say we are in the Father or in God. The Church would not be called the body of Christ, it would be called the body of God. It is the body of God. If He wasn't God, people would not worship Him we would recognize him as we do Moses or David.
I would have a completely different concept and focus if Jesus was not God.
