Many church things, we do so often that we stop understanding the reason behind them. This comes up from time to time in the life of the church, when we wonder about certain traditions or special events, but the fact is we do the same with the Sunday morning service itself. We do it every week. We think its important to do, but do we stop to think why we do it? Psalm 100 serves as a way of reminding us what is actually occurring in worship. We encounter the presence of the Living God. We may see God other places during the week, but we know that God, the creator the universe, is literally there in worship every week. To me, this way of seeing it raises the stakes for what is really going on every week.
