In my opinion anyway the last verse goes quite nicely with the others!
A couple thoughts on the poetry angle; (Feel free to ignore them if they clash with your poetic preferences 🙂
-In verse 1 two lines end with the same word: believers.
– “the Comforter from Christ rained down” this line sounds a little odd to my ear. As does “who had been His believers” ( Again this is just my ear so if your ear likes it just ignore my remarks.)
Verse 3 “His spirit quickens everything” seems like it sound a bit awkward.
