Many great people have claimed to be something great! How does one know that what Jesus Christ claimed to be is true? We don't need to take His word for it, if that is a problem for you, because John the Baptist, the works that Jesus did, and the testimony of God the Father all speak and verify Who Jesus Christ is...if you have a problem with Him it is not because of the lack of evidence or testimony concerning who He is, it is because of a problem with you.
