I googled this same question and found this convo, so figured I’d add my two cents. I too moved from the DC to Texas and it is a very common saying in black churches down here. I hadn’t heard it before in 40 years of living in DC. They use it so much down here, and after 4 years of hearing it, I had to look it up, as it had me wondering if I wasn’t aware of another correct usage :-)
