There is much that Muslims and Christians differ on. Fundamental to our differences is the Deity of Jesus. According to the Qur’an/Islam, Jesus was a messenger of God (rasul), much like Muhammad. According to the Bible/Christianity, however, Jesus is the eternal Son of God, who became a man (the incarnation; e.g. John 1:1-18; cf. Ephesians 1:3-14) to accomplish the salvation of God’s people. I recently discovered an article on an Islamic website that attempts to argue against the Deity of Jesus. I have just finished my response to it. You can view a PDF of both the article and my response here: “Is Jesus Really God?”: Defending the Eternal Glory of Jesus against the Objections of Islam
