Allen made reference to this at our business meeting on Tuesday night, but it is worth reading the article in full if you haven't ever done so.
The Family Together in God's Presence was written by John and Noel Piper in the 90's but I feel like it could have been written 50 years ago or 3 years ago. In my experience, families used to do this back in the day and families just started doing this 3 years ago. We are some that started doing it 3 years ago and have learned so much since then.
I think Piper sums up what we have learned very well and Noel gives some wonderfully practical tips on how to do it.
