An extended biblical investigation by Central Seminary alumnus Chuck Bumgardner. Here is his conclusion:

Now, these passages are not, strictly speaking, “prescriptive” (as we may think of that term); they do not command with an imperative that worshippers of God must assume one or another posture. But it is instructive that in this sampling of passages, if anyone is sitting, it is God! Worshipers—in these passages at least—are portrayed either as bowing or standing. What implications does this have for our worship services, and our singing praise to God?
