What T-Block has posted is good...but IMO half the feel of Gospel is in the rhythm. If you play straight-ahead jazz, bebop with a lot of runs, or styles like Herbie Hancock or Chick Corea there's not a lot of swing.
In contrast, 1950's Classic Gospel relies on Blues harmonies and lots of triple time (6/8-9/8-12/8) beats. Even the 4/4 songs often have a "shuffle" feel. Think Ray Charles, Elvis or doo-wop.
More contemporary Gospel songs rely on the styles current at their time. Right now it seems to be lots of neo-soul Jazz-influenced 'crazy' chords and runs, mixed in with some aspects of Rap and Hip-Hop, like similar sounds, repetitive melodies and chord changes, production values.
But at the same time there is a Gospel 'punch' in keyboard articulations, a feel quite unlike Classical or Pop or even smooth jazz...listen to the first song in MJ's funeral, the piano/choir rendition of Andrae Crouch's "Soon and Very Soon" for a taste of this...
