The "room God walks through" on streets is decidedly on earth; not heaven. There ARE no streets in heaven...there is ONE street; that's precisely the point (I know you were taught in well-meaning Sunday School classes about "streets of gold," but a quick Bible check will correct us). It's Kingdom come on earth (partly and propleptically)as it is (perfectly) in heaven; but the streets are in Dublin; Ethiopia; New Orleans, and most recently Africa (watch this and weep!)
So in a delightful irony, a song that many believers intuitively knew was about the Kingdom of heaven invading earth, has been critcized by conservatives for lacking its previous "spiritual context" in its current tour version. Why? Because the opening prayer is about Africa; not a biblical Psalm as usual. Give me a break, please. What does the Kingdom have to do with Africa?! What does a question like that have to do with Christianity!
