On your way to church, be sure to wave hello to everyone, especially babies and dogs.
When you arrive to church, run through the halls greeting everyone hello, especially the office workers. Take your time. Even though the bulletin lists worshipping starting at 10, this is merely a suggestion. There is always time to say good morning.
Run into the sanctuary and go straight to the front. Smile and wave to your pastor, but do not walk up the two steps to the altar. Stand in front and look at the cross and altar with awe.
Bring friends: there is always room at God's house for more, even baby dolls and stuffed animals.
Sing loudly and joyful whatever is in your heart...whenever the spirit moves you.
Empty out all the money of your wallet into the offering. Trust God to take care of you.
Take turns sitting with everyone in the congregation. There is not such thing as "your pew." For extra fun, find a new spot after each song, prayer, reading, etc. Nobody should feel lonely on Sunday.
Question everything.
Get close. Get close to people. Get close to the altar. Get close to the organist. Get close to God.
Smile and dance during communion. This is the feast of our Lord and not some somber party.
