Really good worship, when it's loud and it wraps around you and you're among hundreds of people also worshiping at that exact same time, is when I feel God. It's when all doubt and sadness fall away because I stand there and I can't deny the chill bumps I get on my arms or the tears that are coming to my eyes.
Right now my favorite is "Mighty to Save." So here it is in the form of a cute teddy bear. Crank 'er up.
