"So often in the Psalms we find expressions very similar to this one: "Great is the LORD and greatly to be praised." When you break it all down, true worship is simply catching sight of the greatness, majesty, glory, and grace of an infinite God. When God is not greatly praised, it's only because we don't think He's that great of a God. When our worship is small, it's because our concept of God is small. When we offer God little-bitty sacrifices, it's because we've somehow reduced him in our hearts to a little-bitty God. Our vision has become clouded, our hearts distracted."- Louie Giglio
