The former UFC champ hit up the B&GC in Albuquerque, New Mexico -- where he talked to the kids about the importance of working hard to make their dreams come true.
But the best part -- one of the kids challenged Jon to play the UFC video game on Playstation ... AND CRUSHED JONES (who was playing as himself).
Sources close to Jones tell us ... Jon has been working hard to get his life back in order ever since his hit and run arrest -- doing volunteer community service and spending lots of time in the gym.
As for resuming his MMA career, we're told "nothing's out of the question" -- but he's been focusing a lot of his time on mentoring and coaching other fighters.
Jones is still suspended from the UFC -- but check out this recent video of Dana White (below) ... it's clear he's still a fan of the guy and if he keeps up the good work, we're guessing we haven't seen the last of him in the octagon.
