It seems like a very thought-provoking song, from the point of view of one who is honestly looking for answers regarding God and His nature. I've heard it before, and can remember when it was popular. Around about that time, I recall one Christian periodical labeling the song as "sacrilegious" or "blasphemous", but for some reason, I do not get that. I certainly can understand that the song can make some believers uncomfortable in their spirits, and for that reason, such people are better off not listening to it. So, I can see it from both sides; everyone reads things differently.
The song actually poses a legitimate question from the unbeliever or seeker point of view. However, I am inclined to agree with many posters that God, relating to us in the intimate way He does and working through us as believers to be His voice to humanity, is one of us!
God is also devine and all-powerful, and anyone who becomes a Christian will grow to know and understand that.
