In an age of global terrorism and rising religious conflict, it's significant to note that all Muslims regard Jesus as a great prophet...
The Secret Message of Jesus, p. 5
The question of any "age" does not in the end mean anything (and how is this age different from any other in regards to religious violence). The truth is, while Muslims may regard Jesus as some kind of prophet, they do not believe that He is the Son of God, they do not believe that He was crucified, and they do not look to Him for redemption from sin and for salvation.
I John 4:1-3
Beloved, do not believe every spirit, but test the spirits, whether they are of God; because many false prophets have gone out into the world. By this you know the Spirit of God: Every spirit that confesses that Jesus Christ has come in the flesh is of God, and every spirit that does not confess the Jesus Christ has come in the flesh is not of God...
I John 5:10-12
He who believes in the Son of God has the witness in himself; he who does not believe God has made Him a liar, because he has not believed the testimony that God has given of His Son. And this is the testimony: that God has given us eternal life, and this life is in His Son. He who has the Son has life; he who does not have the Son of God does not have life.
