Can Muslim Converts to Christ Still Use the Name "Allah" for God?

Bible Q&A with John MacArthur

QUESTIONER: Thank you.

JOHN: Yes. Go ahead.

MARISA: My name is Marisa Hernandez. And my husband and I are missionaries to Arabs and we've been approached by Christian Arabs in this congregation with this question. Allah is the name that thousands and millions of believers in Jesus Christ use for God. As an Arabic speaker, I sing many praises to Allah in the name of Jesus. I was missionaries to Muslims in the Middle East for four years, and I led Muslims to faith in Christ by explaining to them the true character of God, Allah, as explained in the Bible. Will you clarify why you say, "Allah is another name for Satan," without any explanation or disclaimer that all translations of the Arabic Bible use Allah as the name for God?

JOHN: Yes, that's a very good question. Allah is another name for Satan because the Allah, the Allah of Islam, is not the true and living God. When you...you have to be very careful when you go into a missionary effort with people. By taking their deity and somehow turning that deity into the true God, you create a confusion.

The fact of the matter is all false religions have a god or gods. And to call some entity of your own manufacturing or some demon or Satan himself "God" doesn't make it so. And the Allah of Islam is not God. It is not the God of Abraham, Isaac and Jacob. It is not the God and Father of our Lord Jesus Christ. Now if you use...if you speak in their language, Al-Elah, the God and you take the uppercase letter down and you say let me introduce you to the real God who is not the god of Islam, now you're getting on a right footing.
