Hi Jo,
When reviewing a lyric that has no accompanying melody (so far), one important thing I look for is consistency in the verses. So I compare the verses, line by line, to see if they will fit the same melody. Your verses have some inconsistencies but, for the most part, they can be made to work. One line I can't bend to fit, without it sounding awkward, is "when friends have deserted me", so that line might benefit from a little more thought.
I have a bias against using the word "that" to refer to a person (or, in this case, Supreme Being), so I do recommend considering changing "that will be just like you" to "who will be just like you" and "that rules with humility" to "who rules with humility". In my mind "that" refers to things, not people (or God).
I noted the reference to the word "lamb" in another post, and I assumed you used that word to identify this as Christian; however, if you're interested in "God-like" alternatives, you could try "King", or even "Father", although that second one adds a syllable which may throw off the meter of your line.
That's all I have at the moment. I hope it's helpful!
