I will be their God.Jeremiah 31:33
Christian, here is all you require. To make you happy you want something that shall satisfy you, and is not this enough? If you can pour this promise into your cup, will you not say, with David, "My cup overflows."1 When this is fulfilled, "I am your God," are you not possessor of all things? Desire is insatiable as death, but He who fills all in all can fill it. The capacity of our wishes who can measure? But the immeasurable wealth of God can more than overflow it. I ask you if you are not complete when God is yours? Do you want anything but God? Is not His all-sufficiency enough to satisfy you if all else should fail? But you want more than quiet satisfaction; you desire rapturous delight.
Come, soul, here is music fit for heaven in this your portion, for God is the Maker of heaven. Not all the music blown from sweet instruments or drawn from living strings can yield such melody as this sweet promise, "I will be their God." Here is a deep sea of bliss, a shoreless ocean of delight; come, bathe your spirit in it; swim an age, and you shall find no shore; dive throughout eternity, and you shall find no bottom. "I will be their God." If this does not make your eyes sparkle, and your heart beat fast with bliss, then assuredly your soul is not in a healthy state.
But you want more than present delights--you crave something concerning which you may exercise hope; and what more can you hope for than the fulfillment of this great promise, "I will be their God"? This is the masterpiece of all the promises; its enjoyment makes a heaven below and will make a heaven above. Dwell in the light of your Lord, and let your soul be always ravished with His love. Get out the marrow and fatness that this portion yields you. Live up to your privileges, and rejoice with unspeakable joy.
