The two old friends met up recently and now God-fearing Slim tells TMZ Kanye could be developing a big Christian project.
"We talked about a lot of things," he told the outlet, "Things spiritually he's involved himself in."
And the 112 star hopes the "Jesus Walks" hitmaker is serious about re-releasing some of his tracks with a more Christian vibe, adding, "It draws the youth to the church; it makes church cool."
"Whatever happens, it's something that God wanted to happen."
And Slim has assured fans that his rapper pal appears to be good after many felt he'd lost the plot last year as he offered up support to U.S. leader Donald Trump and suggested slavery was "a choice" for African-Americans in TV interviews.
"He's (Kanye) in a real good place," he explained.
