[how do I profit or gain from discipling another man of God on how to walk faithful to God?]

I would like to get some opinions or even scripture reference for this question. What profit or gain is there for a man of God to disciple another man of God, from the discipler's point of view? In other words, how do I profit or gain from discipling another man of God on how to walk faithful to God? I am trying to sell this point to enlist men of God to volunteer to disciple other less mature men of God. Thanks for your help. Phil
