Your experience of “what church is” is primarily a two-dimensional experience—being a spectator at a weekly meeting—but in a more entertaining setting.
The primary focus of the meeting is still a lecture, but it is a more engaging lecture, which may contain lively descriptions and stories, and appeal both to the emotions and the intellect. The topic will often not be doctrinal, but Christian Daily Living.
The music will be more contemporary in style, and may reflect emotions of the song writer ABOUT his relationship to God. There may even be an interactive session, in which you may have an opportunity to briefly give your opinion about some topic or scripture under discussion.
Your interactions with most of the people in the group are still only brief encounters after the service, or after a similar meeting later in the week.
If the church is involved in any outreaches of evangelism or charity, they will be initiated and organized by the few in leadership positions, with volunteers solicited to assist them.
