I think it means that his own father walked out on him when he was little and he never had a father growing up, and watching his friends around him hang out with thier dad's and have that father-son connection hurts him. He asks him basically if he remembers walking out on his family and tells him that he will never know what it was like to see him grow up into a man. He had no where to turn so he accepted god as his savior and now has someone to turn to instead of his actual dad.Someone to help him through everyday challenges and a hand to guide him through life.
