as nothing else happened, my humble 2 cents:
this song and the singer / musicians are good, so it is worth remixing.
depends on the purpose, maybe not quite a big commercial release, but great for the singer and the community..
here is what I would likely do...
you could take the live vintage/church approach, with more of this lower midrange in the drums, and some over all reverb and delay.
I think it is a case of a couple instances of LinMB
the epiano has a bad decay, it is kind of stumbling down at every note. with its own reverb, and mid-range compressor it could be more flowing.
with the drums, you could softly compress bass and lower mid with a multiband, but not the high bands. then the dynamics can be restored with fader programming.
drum reverb is too "modern" and pop. longer pre-delay, less density and high range (=more roll-off). try "church" setups and make them small enough to keep it transparent...
the voices need an amount of fader automation, too. some stereo delay could make the background voices stronger.
if you detect distortion in the recorded vocals, it will become a swiss knife EQ job. some parts are quite harsh.
I would play around for a while, the sound will not become particularly clean and perfect, but it may develop to a beautiful gospel listening, from the music.
I think, the material is underestimated.
