No doubt, this is one of the biblical doctrines which is attacked the most. If the Devil can convince a person that Jesus is not God, then we do not have a Saviour; then Jesus would merely have just been a good man. The following groups do not believe that Jesus is God: Jews, Muslims (Moslems), Jehovah Witnesses, Mormons.
Scriptures which prove Jesus is God in the flesh:

Isaiah 9:6: For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counseller, The mighty God, The everlasting Father, The Prince of Peace. 7: Of the increase of his government and peace there shall be no end, upon the throne of David, and upon his kingdom, to order it, and to establish it with judgment and with justice from henceforth even for ever. The zeal of the LORD of hosts will perform this.

John 14:8: Philip saith unto him, Lord, shew us the Father, and it sufficeth us. 9: Jesus saith unto him, Have I been so long time with you, and yet hast thou not known me, Philip? he that hath seen me hath seen the Father; and how sayest thou then, Shew us the Father? 10: Believest thou not that I am in the Father, and the Father in me? the words that I speak unto you I speak not of myself: but the Father that dwelleth in me, he doeth the works. 11: Believe me that I am in the Father, and the Father in me: or else believe me for the very works' sake.
