what happens in Tom's cabin after their evening meal? Why are Tom's prayers appreciated by the other slaves?

The cabin is then filled with slaves who are convening for a religious meeting. The slaves first gossip about the rumors concerning a slave trader's visit to the plantation, and then the religious service begins. The ceremony is full of energy, laughing, crying, and singing. Tom leads the slaves in prayers full of "touching simplicity" and "child-like earnestness."All the slaves appreciate Tom's sincerity.
