You can change the outside of a man and still leave the inside untouched. You can look strong, talk right, even sit in church—and still have a heart that isn’t guarded. Solomon said it this way: “Keep your heart with all vigilance, for from it flow the springs of life.” Not just hear the Word. Not just look the part. Guard the heart—attentively, vigilantly, carefully. Because the heart of the matter is always the matter of the heart.
