Be a bit careful about “what can we learn from communists.” These fallen systems ARE ripoffs of God’s plan, but any insight thereby gained needs to be run through the screen of God’s Word.
People have taken God for granted, instead of as the one Who truly does earn the name “Wonderful.” It’s as though you had a gold mine in your back yard and you only dug in it with a teaspoon.
Behold I send you as sheep in the midst of wolves. Be ye therefore wise as serpents and simple as doves.
