(Proverbs 27:19 KJV) As in water face answereth to face, so the heart of man to man.
“Heart” (3820) is a good translation here as long as you understand it figuratively. The Hebrew word is used to refer to the inner man, the will, the core of being. Thus when we talk about a “hearty” soup we don’t mean that it was made with that organ but that it is a rich, complex stew that offers a wide range of satisfaction. The opposite would be thin not French onion. Unlike soup, the heart cannot give off a robust aroma and be weak at the same time.
Jesus insists on reaching down into our inner man, our heart. A little child may think of Jesus as physically entering our blood pump but a mature mind understands that what is filled, what is cleansed and what is given is the inner core of our being. Our hearts should reflect Jesus.
So? Have you allowed Jesus to transform your mind or are you still satisfied with the reflection of a mirror? Our role model is not Narcissus by the pool but Paul on the road to Damascus.
