If you read the passage in context, to whom was Jesus referring before the passage and after the passage? Was Jesus speaking of Israel or members of His Church? Or is there some other to which He was referring that you might want to clarify for us?
Oh, by all means, I forgot that Christ was talking to a physical patch of dirt, not to a people, a people who Christ says there are none of in Christ. Sure, Christ was talking about trees on a hillside and giving gardening tips.
Gotcha !!! LOL. Wolves in sheep's clothing are so funny when they get desperate and evasive.
