Thousands of people are filling the fairgrounds for the Tulsa Workshop.
More than 200 exhibitors include authors, missionaries and universities. The event is filled with workshops from Christian speakers.
Memorial Drive Church of Christ minister Terry Rush is learning a lot to take back to his congregation.
"The Christian world has got to get better at what we're supposed to be doing -- and that is to learn to love, to love God and to love people much more effectively than we've done in the past," Rush said.
The Tulsa Workshop is free and runs through Saturday.
