He spoke parables that He didn't interpret. But He said they were parables. Regarding the Parable of the Sower, Jesus said that if they didn't understand that one, how would they understand any of them? I understand that to indicate that the key to understanding the parables is found in that one.one thing I have noticed about a parable or allegory. Even when jesus spoke. he gave us the interpretation of what it really meant
If we do nto see an interpretation given, we should take it literally
We're told that there was a time after which Jesus only taught the crowds in parables, but to His disciples, He still taught plainly. So we can "rightly divide" by understanding these things.
Much love!
