Sharing personal experiences with a group generates feelings of belonging. Conversational prayer - talking to God builds unity by praising Him and by praying for expressed needs. Bible application - teach to encourage a relationship with Jesus rather than the Christian culture. Encourage participation without pressure. The leader is a guide of the side rather than a sage on the stage.
Interactions are easier if people can see one another.
Avoid calling on people to read aloud or reading around the group. Contact ahead of time those you want to read aloud. Respond immediately to an expressed need. Love responds immediately. Pray for the individual and need as it is expressed.
