Justin Bieber is letting God do his talking ... posting a photo of several Bible passages in the wake of the latest video of him using the n-word.
TMZ posted the video Wednesday ... showing a 14-year-old Bieber singing a racist version of his own song, repeating the line ... "There'll be one less lonely n*****."
Bieber's camp wanted the video out so he could own up to what he'd done.
Bieber's Instagram post focuses on 3 verses -- 2 from the book of John and one from Isaiah -- and all of them deal with forgiveness and salvation for your sins.
His manager Scooter also posted this.
