I have always said that I like my poetry to be short and sweet, but this was just a bit to compact for my tastes. There was little description of this "beauty of God" and there were absolutely no comparisons, similes, metaphors, etc. that make poetry more than just a few lines to say what's on your mind.
I agree that you used true and truly too much in such a short poem, and i'd also like to comment on the fact that the word seen ends two seperate lines in an 8 line poem.
I would work on it, explain this "beauty" in a way that the reader can better understand (because there are so many meanings of beauty) and use more concrete, sensory details to give your writing roots in the minds of the average reader that can't just know your thoughts and intentions.
though this is extremely short and simple, i enjoyed reading this. the only little itty bitty nitpick i have is that with this being as short as it is, you use the word "true and truly" a little too much
but now with eyes from without
i'm also not sure if that is suppose to read Now or Not....personally i think Not would seem better, but that's my opinion
