Memory is frequently the slave of despondency. Despairing minds remember every dark prediction in the past and expand upon every gloomy feature in the present; in this way memory, clothed in sackcloth, presents to the mind a cup of bitter-tasting herbs.
There is, however, no necessity for this. Wisdom can readily transform memory into an angel of comfort. That same recollection that on the one hand brings so many gloomy omens may be trained instead to provide a wealth of hopeful signs. She need not wear a crown of iron; she may encircle her brow with a tiara of gold, all spangled with stars.
Such was Jeremiah's experience: in the previous verse memory had brought him to deep humiliation of soul: "My soul continually remembers it and is bowed down within me"; but now this same memory restored him to life and comfort. "But this I call to mind, and therefore I have hope." Like a two-edged sword, his memory first killed his pride with one edge and then slew his despair with the other.
As a general principle, if we would exercise our memories more wisely, we might, in our very darkest distress, strike a match that would instantaneously kindle the lamp of comfort. There is no need for God to create a new thing upon the earth in order to restore believers' joy; if they would prayerfully rake the ashes of the past, they would find light for the present; and if they would turn to the book of truth and the throne of grace, their candle would soon shine as before.
Let us then remember the loving-kindness of the Lord and rehearse His deeds of grace. Let us open the volume of recollection, which is so richly illuminated with memories of His mercy, and we will soon be happy. Thus memory may be, as Coleridge calls it, "the bosom-spring of joy," and when the Divine Comforter bends it to His service, it is then the greatest earthly comfort we can know.
