What is the best way to convert a christian to Islam?
I'd first prove to them that trinity is a man-made lie. See Answering Trinity section where every single so-called "trinitarian verse" in the Bible is refuted.
Then, I'd prove to them that the Bible is corrupt and was altered by the Church and men.
Then, I'd show them What parts of the Bible do Muslims believe are closest to the Truth, and why?
Then, I'd prove to them that Muhammad and the Religion of Islam were foretold in the Old Scriptures.
Then, I'd concentrate on the Oneness of GOD Almighty and stress it out real good to them, because it is the only mean for Salvation -- is to believe in GOD Almighty as the One True Living Undivided GOD and King.
Then I'd then show them the place and status of Jesus, Jews, Christians and non-Muslims in Islam.
If they start sharing their personal stories about how GOD Almighty saved them from danger or trouble, and how the Holy Spirit was there for them and inspired them, then I would tell them that Allah Almighty can still reward a person and set the conditions to save them from trouble, because He does it all the time even to non-Muslims and non-Christians too, because He is the Most Merciful. See also The Holy Spirit in Islam.
Also, Karma (what goes around comes around) does exist in Islam.
Also, GOD Almighty tests people: Why does GOD give the arrogants and wrong-doers much power in life and takes it away from the good people?
Last and not least, I would finish off their doubts and fears by giving them The Overwhelming Scientific Miracles in the Noble Quran. These are GOD Almighty's Divine Signatures in the Noble Quran to prove to us today that the Book is indeed from Him!
Indeed, all Praise and Glory are due to Allah Almighty alone for making the Noble Quran be the Perfect and Everlasting Miracle, for us humans, out of all of His Divine Miracles! And may Allah Almighty send His Peace, Mercy and Blessings upon our Beloved and Blessed Prophet, Teacher and Role Model, Muhammad. Ameen.للمزيد من مواضيعي
