Why do some Christians hold each other's hands when they pray? That is a common practice most of the members here have during private settings when giving thanks at meal time, visiting the sick, etc. I just accepted and never questioned it.
Answer:I suppose they do it to make them feel more united and closer to each other when offering a prayer to God. I don't know of any biblical basis for the practice. The closest I can think of is the laying of hands on someone who is being prayed for as a show of support and acceptance (Acts 13:3). At the same time I can't think of any harm in the practice either.
