(Proverbs 10:8 KJV) The wise in heart will receive commandments: but a prating fool shall fall.
The word “heart” (3820) is very common. It is used almost 600 times in the Old Testament. The translation has to do with our use of the heart as the center of our being and emotions. That is the way it is used. I don’t know if the Hebrew word is ever used of the physical organ like it is in English and I am too lazy to go through 595 references to find out.
This word points out that the believer and the life of faith is a total package. It is not just the physical world and our actions. It is the inner world and our motivations. It is not just eternity, but the here and now too. It is not just what we say, but what we believe. This is why the put downs of “pie in the sky” and “opiate of the people” are just nonsense. Faith in Christ is pie in the person too. It is the hope of the people.
So? Living by faith is not whistling in the dark, it is wisdom. It is the sign of a solid foundation. It is the first step to eternity.
