I understand that the Arabic word for God is “allah.” Perhaps it would be best to say, “The Muslim’s ‘Allah’ is not the one and only true God. But most of the arabic people of the world are Muslims.
Your explanation is true. Peter and Paul went to the Jews first, then the Gentiles, as the apostles were told by the Lord to do. A third “category” of people was specifically singled out in Acts—the Samaritans. People of all three “categories,” to whom Jesus was to be preached, received the message, were saved from their sins, and baptized (united) by the Holy Spirit into one body, of the Lord Jesus Christ—called the Church, and are still being saved in the same way.
As far as the “categories” named in the Scriptures, the
arabs would be Gentiles. Wonder how the Muslim arabs would like that term—Gentiles—applied to themselves...
“The Muslim’s ‘Allah’ is not the one and only true God.”
I agree when you word it that way. If we just think of Allah as the Arabic word for God, then the correct descriptions will automatically happen.
No one here would say “God is the Devil”. But we can say Muslims unknowingly serve the Devil.
