Learn the importance of guarding your heart. It is vital to understand how to “guard our hearts” as Proverbs 4:23 instructs us “for out of it flow the issues of life.” The Hebrew word leb used in this verse, which is translated “heart,” occurs almost 600 times in the Old Testament. The term leb is very general, referring to many aspects of our being, including our mind, will, understanding, soul, memory, will, passions and the place where we feel courage. The heart at our core or mid-section is also where our conscience resides, together with the center of our emotions, moral nature and spiritual life—which, as we learn in John 7:38, flows out of the belly.
