Why We Must Guard the Heart
We all have things we treasure, whether they are prize objects, activities, or experiences. And what we most value is what is closest to our heart.
Proverbs 4:23 admonishes us to keep watch over our heart because it holds our treasures, and in it is potential for good or evil. Originally, the heart is full of wickedness (Jer. 17:9), but when it is purified, we are able to see the very face of God (Matt. 5:8). With such possibilities within us, is it any wonder that we are exhorted to employ all diligence in guarding our heart?
So how do we remove the impurities and uncover those secrets of the heart spoken of in Psalm 44:21? The answer is through our omniscient Father. He knows what litters the landscape of our hearts. He tells us in Revelation 2:23 that “I am He who searches the minds and hearts” and again in Hebrews 4:13 that “all things are open and laid bare” to His eyes.
Our role in all of this is to ask the Lord for help. We may not know what sin lies within, but He does. Like David in today’s psalm, we too can say, “Search me, O God, and know my heart ... and lead me in the everlasting way” (Psalm 139:23-24).
