"How's your youth ministry going?"
"We don't have any youth ministry."
"I thought you had a handful of grade 8 people that got together after the service on a Sunday."
"Yeah we do, but we don't have anything on a Friday night."
Some people think a Friday night youth group is the main game and unless you have a group then your not doing real youth ministry.
I would suggest that it doesn't matter what day, time, where or the amount of young people you have.
As long as you are making disciples then be encouraged you are doing the right thing.
Look around you, who has God given you to disciple, there's your youth group.
