Hear and Play Guitar Gospel 101 with Bobby Griffin a while back. It's a good video for beginners to intermediates.
90% of the video is explaining the chord progression below, and how to apply it to various congregational/ hymn songs. Also, he went over the (Gospel) Blues Scale.
Unfortunately, no tabs/ written music is available with the video. He doesn't teach gospel riffs, like Dubose or Eric Halls play. I guess that would be Gospel (1001)
So don't buy this video expecting it to teach you to play like an expert. You will be disappointed

Only diligent practice can get you to an expert level.
Overall, (from scale 1 to 10) I give the video a "7"
