God made us to live in community, and living in community means communicating. Many people send and receive messages by using their voices and ears and brains. That's not to mention the emotional messages that go back and forth between communicators: how you're feeling today, past experience, if you're in pain or not, reading body language and tone of voice.
Is it any wonder that providing a meaningful, genuine worship experience electronically is a challenge? What's the audio source? Who needs to receive it? How? What's the video source? What's the best angle? How do you include people who are worshiping online and people in the building? And what if the answers to those questions are different than last week's answers?
