Muslims say that the prophets preached the oneness of God only. They never predicted God’s son to be born. Christians don’t worship God instead they worship Jesus. They pray to Jesus instead of God. What’s your response?

If this is what Muslims say then they are just plain wrong.  They are mistaken.  In Isaiah 9:1-7 we have what is a clear messianic prophecy which describes where Jesus would come from, and follows by describing him as a Son and as mighty God.  “In the past he humbled the land of Zebulun and the land of Naphtali, but in the future he will honor Galilee of Gentiles, by the way of the Sea, beyond the Jordan…  For to us a child is born, to us a son is given, and the government will be on his shoulders.  And he will be called Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace.”  Here we have a clear messianic prophecy in which the Messiah is called both a Son and Mighty God.  Perhaps some Muslims might claim that this is not a messianic prophecy, but it quite clearly is, and besides, this amounts to circular reasoning.  In other words, any prophecy which talks about God’s Son they will simply deny that it is messianic.

Another relevant prophecy is Isaiah 7:14 in which we are told that “the Lord himself will give you a sign: The virgin will conceive and give birth to a son, and will call him Immanuel.”  Immanuel means God-with-us.  In other words, there will be a child—a son, who will be God with us.  Again, we have a clear reference to a Son of God who is himself God.

This statement is simply not true, and Muslims ought to stop making these false claims.  Christians do worship Jesus, and they understand Jesus to be God, because this is what he claimed about himself (John 8:57-59 and John 10:29-33 for example).  Now, Muslims can claim that Jesus was a liar, but not that he did not claim to be God.  The problem with this is Muslims believe Jesus is a prophet.  Prophets to not lie.  Therefore the Muslim has to decide: Is Jesus a prophet as you say, or is he a liar, as you also say, given that he claimed to be God and you say he is not.  Jesus was prophesied to be God-in-the-flesh, he claimed to be God, and he worked wonderful miracles, such as raising Lazarus from the dead and, upon being crucified, being himself resurrected.  Besides, even the last claim is misleading.  It is true that some Christians pray to Jesus, but most Christians pray to the Father.  However, they also understand, correctly, that Jesus is God—he is God’s Son (John 1:14-18).  Literally every single word in this Muslim criticism is false.
