What the Bible says about Unity Better than Singularity
(From Forerunner Commentary)
He intimates that three are better than two. There is nothing wrong with that, but it is showing the principle that unity is better than singularity, and as people who are likewise unified with those who were there before, the institution, the family, or whatever, keeps getting stronger and stronger. As long as all of the minds are undivided, they add to the strength of those who are already there.
