Willie Myrick recounted the story at a recent gathering in his honor. He says as he sang, the man drove around and was cursing before eventually letting him go unharmed last month.
WXIA-TV reports that Grammy Award-winning gospel singer Hezekiah Walker, who performed the song, traveled to Atlanta to meet the boy.
Walker says he believes God spoke through him to save the boy's life.
Police have a sketch of the suspect and are searching for him.
More details on what the boy told police about what happened on March 31 weren't available.
