David may believe his desire to upgrade God from tent to temple is all about God but truth is David is embarrassed that Israel’s God is housed in such a humble abode. More to the point, such a humbly housed God is a poor reflection on the new king on the block which is why David needs God to move uptown into a temple of gold and stone and cedar. We lust after bigger buildings and consider churches that house ten thousand more significant than "two or three gathered in my name" who love the Lord with their whole lives. The church may be built to glorify God but it magnifies the power and prestige of the humans that build it. If bigger is better why did God choose a manger in a stable and an unwed teenage girl to birth the Messiah into a world that would despise his teaching so much it would attempt to shut him up by nailing him to wood? The upgrade God desires is not a church made of stone but a permanent dwelling place in your heart.
