Jesus did say we should keep the commandments, in spirit and in truth (Matthew 19:16-17). But neither Catholics or Protestants keep the commandments! They reject the plain truth of the Bible to keep their idolatrous traditions.
I asked my friends (who said we should "just keep the 10 Commandments") whether they were ready to stop keeping Sunday and start keeping the Sabbath - to "remember the Sabbath to keep it holy." Apparently the question caught them off guard as neither replied. How about you? Will you keep the commandments, so help you God, including the Fourth Commandment?
