In this scene from the show, the gamblers are at a prayer meeting and they are invited to share their testimony. They are strongly invited to stand up and tell why they are there and what they want to change. Some of the answers are silly. When it gets to Nicely, he makes up a dream about why he won't be let into Heaven (he drinks and gambles even on the way to Heaven). In the dream, he is messing with the journey and people are asking him to sit down, to stop making waves.
I can sympathize with Nicely, I tend to rock the boat. I want to shake things up and push people into seeing this vision I have of a world where God is there with you asking you to stand up and speak out against injustice, to work to change poverty and hunger, to invite people into a relatonship with God that will transform who they are. We are to rock the boat, when we get a little to comfortable with the world as it is, verses the world God dreams where the lost, the last, the least are invited to the party. A party where the wine flows freely, the laughter is loud and the joy abounds. So I hope you spend a little time rocking the boat.
