In the end, worship can never be a performance, something you're pretending or putting on. It's got to be an overflow of your heart...Worship is about getting personal with God, drawing close to God.
The heart of God loves a persevering worshipper who, though overwhelmed by many troubles, is overwhelmed even more by the beauty of God.
We can always find a reason to praise. Situations change for better and for worse, but God's worth never changes.
