If born-again believers align themselves with the Muslims prophet Jesus of the Koran our Bible becomes a lie and untrustworthy. The Jesus of Islam is their Messiah Mahdi's executioner who will kill Jews and Christians. There can be no compromise or unity of faiths between Christianity and Islam...they are two seperate ideology's.
Islam's Jesus is not the only way, truth and life back to God. Believers must be wary of the great deception that will come upon the world leading up to a One World Religion. Know what your Bible says and means, II Tim. 3:16. Stay in the Truth of His Word and don't be fooled by Satan's clever tricks and schemes. Love the person (Muslim) but do not compromise the faith for the sake of unity. Our Jesus of the Bible is the only Way, Truth and Life and we must always stand firm in our faith in Christ no matter what the world is telling us to do.
