As usual my comment went to spam. I should make lights with all the canned meat containers that I generate. Here was my comment:
What should a 'Christian' learn? Each should learn how to live - .e.g the fear of the Lord, the knowledge of good and evil (Psalm 34). Or what Yhwh does (Psalm 146). No self-protective confessions. Each should learn to be as a child -
Is it should or must? It's a lifetime's learning - far more than 20 min (or less) a week.
I would (of course) recommend the poetry of the Psalms...
