I don’t know about you, but I don’t believe that, and David certainly didn’t believe it either. In his final charge to Solomon, he challenged him to remember God: "And you, my son Solomon, acknowledge the God of your father, and serve him with wholehearted devotion and with a willing mind, for the Lord searches every heart and understands every desire and every thought." (vs 9)
Is that a comforting thought to you? It certainly is to me. God knows you. And it’s more than just knowing who you are or knowing your name or recognizing your face. He knows you even better than you know yourself. He understands the inner workings of your mind. He understands where your every desire comes from and hears every thought you have.
In addition to that—and probably best of all—He is gracious and merciful and sympathetic. You know, we’re all messed up. And the fact that He understands the intricate workings of your heart only makes Him more compassionate toward you. He doesn’t use this intimate knowledge as ammunition against you. On the contrary, because He understands you so completely, He is the one who is in a position to help you. And He wants to help you.
The only thing that surpasses God’s knowledge of you is His love for you. He knows every hair on your head, He hears every cry of your heart, and He loves every bit of you!
