"Enter into his gates with thanksgiving, and into his courts with praise: be thankful unto him, and bless his name." -Psalm 100:4, KJV.
As we worship God, we need to be coming before Him with a grateful heart. He has given us so much and done so much for us that we should want to show all the gratitude we can for our Savior. As Christians we tend to look at what we can't do instead of what we're protected from. Praise God He keeps us from doing stupid things to ourselves, allowing us to bypass those punishments.
