Today's psalm at Mass is Psalm 23, probably the best know and possibly the most beautiful psalm of all the Psalms. As you know, it starts out this way: The Lord is my shepherd; I shall not want. In verdant pastures he gives me repose; beside restful waters he leads me; he refreshes my soul. Of course, this psalm of David was written about a thousand years before Christ came. After knowing Christ, you feel about the Lord just as David did, if not more so, for it's the same magnificent Lord. There's consistency here. Our God is the same yesterday, today, and forever!
