NO WAY!!!
As I understand it, “allah” is the Arabic word for “god”.
If so, it follows that Bible-believing, born-again, Arabic-speaking Christians call the one true and living God, “Allah.” But, other than perhaps to express some kind of empathy for their Arabic-speaking brethren, there’s no reason for English-speakers to use Arabic language.
Of course, all that matters is what’s in the heart. In the PC-USA church, congregations have been reciting truth for generations. But for many (nowadays, most), it’s only words on a page.
