In "Word Focus" Danny McCain writes:

First Chronicles 16 contains a psalm that is a picture of a time of worship. In this psalm, David identified the key elements of worship.
ELEMENT #1 Giving (vs. 28, 29) First, we are to give God “the glory due unto his name.” The word “due” suggests that we are in debt. …
ELEMENT #2 Remembering (vs. 12-22) Human beings are often not good at remembering. We would rather borrow trouble from tomorrow than blessings from yesterday. David reminded us that worship involves remembering. …
ELEMENT #3 Rejoicing (vs. 10, 23, 31-34) Worship is not a time for sadness. … As mentioned earlier, worship is giving; and in giving is joy. ln worship, we set aside our cares and needs and concentrate on God.
