To love God with all our heart we must first of all will to do so. We should repent our lack of love and determine from this moment on to make God the object of our devotion.
We shall soon find to our great delight that our feelings are beginning to move in the direction of the "willed tendency of the heart." Our emotions will become disciplined and directed. We shall begin to taste the "piercing sweetness" of the love of Christ. The whole life, like a delicate instrument, will be tuned to sing the praises of Him who loved us and washed us from our sins in His own blood. But first of all we must will, for the will is master of the heart.
