The results will not be forgotten any time soon. Jesus is now real and personal to her, and the man will have to reckon on the goodness of Jesus. The same goodness that leads us to repentance. So the seed is sown, God will give the increase. Hopefully this man is reconciled to the Father in time, and the disciple moves out of the category of a forgetful hearer, by doing and becoming a doer of the Word.
How many believers sit in church faithfully every week, and hear sermon upon sermon but not remembering what was preached the week past, and still fail to grasp that James is talking about them and the vast majority of believers. We forget what we heard the past week, how would we remember anything before that? The beauty of doing is you don’t forget, you begin to see Jesus more and more, but it is not necessarily in a dream, it is in yourself, the doer of the Word, being conformed to His image.
