Magnum- How could one even give the impression of supporting such? How could one contribute to the continuing existence of such? It is no "light" matter to me.
Because the peace of God is real. The scriptures are the first to tell you how deteriorated the state of man is, and that it will just get worse. Peace in our hearts is not derived from this world (likely we can all agree on that) nor from within ourselves (altho many bravely try). Peace is a gift from God, according to scriptures. And a peaceful heart gives way to the contentment which you refer to above and puzzles you.
Elderberry mentioned something that I too have observed after several years of commuting with folks of different Christian religions. That it doesn't take much for them to just let go and be content with their circumstances, accepting that a higher power is in control.
It wasn't entirely surprising to see JW making changes and relaxing things, in essence becoming more similar to other Christian religions that aren't so uptight about meaningless things.
Christ said "not much is needed, if maybe only one thing ". It would make sense that even just a little faith (in God, not man who is inferior and confused) could allow for his peace to calm our hearts enough.
