Welcome to Chordie!
Assuming you mean this song:
I grew up with it in church but the video is a slightly different arrangement. I always heard it as a simple three chord song (G, C, D or A, D, E or whichever 1-4-5 you prefer).
Using G the verse is:
Then repeat for the second half of the verse.
Put a D or D7 between the last word of the verse and the start of the chorus such that you're singing "He a-" over it, then play a G on "-bides" (as per below).
The chorus is:
(D) Comforter (optional D7 on -bides; can also do this in the verse)
See how that sounds.
