If You Believe Christ, Then You Must Believe the Bible

I honestly can't understand how someone can believe God and Jesus, but not believe the Bible.

John 1:1 'In the beginning was the Word, and the Word was with God, and the Word was God. 2He was with God in the beginning.'

The Word is God.

John 1:14 'The Word became flesh and made his dwelling among us. We have seen his glory, the glory of the One and Only;'

John 1:18 'No one has ever seen God, but God the One and Only, who is at the Father's side, has made him known.'

Mark 14:62 '"I am," said Jesus. "And you will see the Son of Man sitting at the right hand of the Mighty One and coming on the clouds of heaven."' Jesus sat at the right hand side of God. But in the Book of John, God is at the Father's side. Yet, the Word is God and became flesh. All of this is referring to Jesus Christ who is God and the Word. So who can say they don't believe the Bible, but they believe in God? Who can say Jesus Christ is not God? Such people should reconsider their beliefs...Is this any different concerning the 2nd Coming Christ, Christ Ahnsahnghong who was Jesus 2000 years ago?
