"We sent after them in their footsteps Jesus, son of Mary, verifying that which was before him of the Torah; and We gave him the Gospel containing guidance and light, and verifying that which was before it of the Torah, and a guidance and an admonition for the dutiful. And let the People of the Gospel judge by that which Allah has revealed in it. And whoever judges not by what Allah has revealed, those are the transgressors."
- The Koran, Sura 5, verses 46-47
We find something here in the Islamic Scriptures that I find very interesting. They teach that the Gospel, i.e., what Christians call the New Testament, was given to Jesus to provide guidance to His followers. And the final sentence clearly states that anyone who refuses to judge spiritual truth by the New Testament is a transgressor. There is no indication here of what has become a tradition among Muslims, that the Gospel has been corrupted.
They hold that Jesus was a great prophet. To my mind, that should indicate that what He said of Himself must therefore be taken as truth from God.
John 8:58, "Jesus said to them, 'Truly, truly, I say to you, before Abraham was, I am.'" Here, Jesus claims for Himself the divine Name of God the Father, I Am, found in Exodus 3:14, i.e., the very Torah of Moses that the Koran claims was confirmed by Jesus in the Gospel.
John 10:30, "I and the Father are one." Jesus identifies Himself with God the Father, using again the words of Moses, from Deuteronomy 6:4.
John 14:7, "If you had known Me, you would have known My Father also. From now on you do know Him and have seen Him.” And 14:9, "Whoever has seen Me has seen the Father." Jesus claims that to know Him is to know the Father.
John 16:15, "All that the Father has is Mine." Here is a clear claim to divine omnipresence and omniscience, for they are logically necessary to identify all that is the Father's.
John 17:11, "Holy Father, keep them in Your name, which You have given me, that they may be one, even as We are one." In this portion of what is called His High Priestly Prayer, Jesus again claims a clear identification of Himself with His Heavenly Father.
John 20:28-29, "Thomas answered Him, 'My Lord and my God!' Jesus said to him, 'Have you believed because you have seen Me? Blessed are those who have not seen and yet have believed.'" Here, in a post-resurrection meeting, the Apostle Thomas proclaims His recognition of Jesus as Lord and God! If it weren't so, shouldn't Prophet Jesus have protested against Thomas's declaration as idolatry? That is exactly the accusation that Muslims make against Christians. Apparently, Jesus is guilty of the same sin! But then the Muslim is trapped by his own logic, because a man cannot be a great prophet if he allows idolatry!
My point here is that the very beliefs of Islam, if followed consistently, must force the Muslim to become a Christian. And I will offer the Muslim one ever more-compelling reason, again in Jesus's own words, John 14:6, "Jesus said to him, 'I am the way, and the truth, and the life. No one comes to the Father except through Me.'" Jesus declares that there is no way for access to God in heaven without His mediation. But He also gives this promise, John 6:37, "All that the Father gives Me will come to Me, and whoever comes to Me I will never cast out." We have His promise to receive all who come to Him, that we may know without doubt that we have received eternal life. Is that an assurance that Islam can give you?
