Beautifully poetic words, in a beautiful song. But how many people know what the phrase means? I do, because as a kid I looked up the words and managed to put it together into plain English (which I then penciled into my song book at church for future reference). But I daresay that many people have sung this phrase all their life and don't have a clue what it says.
Nothing wrong with beauty; nothing wrong with poetry. Until it gets in the way.
What then? I will pray with the spirit, and I will also pray with my understanding. I will sing with the spirit, and I will also sing with my understanding. - 1 Cor 14:15
