(Pro 10:17 KJV) He is in the way of life that keepeth instruction: but he that refuseth reproof erreth.
It would seem that there is a parallel between “instruction” (4148) and “reproof” (8433b). At least there is a connection. This reinforces that often we learn by doing. Think of life as an apprenticeship. We learn by doing and that requires correction on the way.
Who does that correcting? We always want it to be the astute, respected icon of wisdom. In reality it might be the family dog looking at you when you forget to feed it. Usually it is somewhere in between. It can also be a question of “what” does the correcting. I have had times when I have been disciplined simply by something I read.
I read. The Holy Spirit talked. I listened. The listening is the hard part.
So? Live and learn. Make progress. It won’t happen unless you cultivate a teachable spirit and expect the Spirit to teach.
