Yep, and the teacher brought it home in how in our thought life the adversary will jump right in with a doubting thought, or an accusatory thought, a thought to attempt to take away His truth.
Seems to go beyond just the preaching of salvation to our very thought lives.
I have enjoyed Dr. Caroline Leaf and her work in neural plasticity, she has taught how, "most people don't think about what they think about", and how important it is to guide our thought life.
Here she is, I hope you are blessed by it-
Thank you kindly
