If you would know experimentally [experientially] the preciousness of the promises and enjoy them in your own heart, meditate much upon them. There are promises that are like grapes in the winepress; if you will tread them, the juice will flow. Thinking over the hallowed words will often be the prelude to their fulfillment. While you are musing upon them, the benefit that you are seeking will insensibly come to you. Many a Christian who has thirsted for the promise has found the favor that it ensured gently distilling into his soul even while he has been considering the divine record; and he has rejoiced that he was ever led to lay the promise near his heart.
But besides meditating upon the promises, seek in your soul to receive them as being the very words of God. Say to your soul: “If I were dealing with a man’s promise, I would carefully consider the ability and the character of the man who had covenanted with me. So with the promise of God, my eye must not be so much fixed upon the greatness of the mercy-that may stagger me-as upon the greatness of the promiser-that will cheer me.
My soul, it is God, even your God, God who cannot lie, who speaks to you. This word of His that you are now considering is as true as His own existence. He is an unchangeable God. He has not altered the thing that has gone out of His mouth, nor called back one single soothing sentence. Nor does He lack any power; it is the God who made the heavens and the earth who has spoken. Nor can He fail in wisdom as to the time when He will bestow the favors, for He knows when it is best to give and when better to withhold. Therefore, seeing that it is the word of a God so true, so immutable, so powerful, so wise, I will and must believe the promise.” If in this way we meditate upon the promises and consider the Promiser, we shall experience their sweetness and obtain their fulfillment.
