The Preacher's Homiletical Commentary
Isaiah 43:19
THE FUTURE BETTER THAN THE PAST
Isaiah 43:19. Behold, I will do a new thing, &c.
God’s messages to Israel are steeped in imagery supplied by their past experiences. From this familiar store the figurative expressions of the text are derived; it holds out a challenge to faith, a rebuke to unbelief.
I. The emphasis of the promise lies in God’s promise to do a NEW thing—i.e., something unprecedented. Israel was cautioned not to make the past the measure of the future (cf. Isaiah 43:18). They were often exhorted to seek help and consolation in remembering their past; but this is a caution against a way of looking at the past which works injury—against a brooding on it that spoils the future. Self-consciousness comes with increasing years; we are apt to exclaim, “The thing which hath been is that which shall be;” “The child is father of the man,” points to the conclusion of a wide induction. Philosophy tells us that this unreadiness to believe that the future can be better than the past is but a proof of growing wisdom; and we are often inclined to say, “our theories of the Christian life have always been far in advance of our attainments; but shortcomings have brought down our expectations.” It is one of the severest penalties of unfaithfulness, that hope for the future is slain.
Often men are not troubled much about the loss of hope, but even these know what it is to have a dark void where there should be a light shining more and more.
One of the hardest tasks of the Hebrew prophets was that of renewing in the people the impulses of hope; and so this representative messenger of God proclaims, “Remember not the former things,” old things may pass away, all things may become new.
II. This new thing is compared with the opening of a path in the wilderness, and the supply of rivers in the desert. Before each one there is a pathless wilderness, beset by difficulties and perils; but even there God will make a way for His people, and sustain their life. Preparation and guidance, difficulty, peril, privation! These are thoughts which associate themselves with the desert and the wilderness. For every Christian, God is preparing a way through unknown experiences. Of each man it may be said—
“He was the first that ever burst
Into that silent sea.”
But God prepares the way; He preserves the traveller; He connects the present, the future, and the past Each day shall be, in some respects, different from all past days; and when the heart turns faint at new demands made upon it, He breathes new life into it with the promise, “Behold, I will do a new thing!” The voice of apprehension cries, “How shall freshness and vigour be maintained within me?” God says, “I will supply rivers in the desert;” not simply sufficiency, but abundance. To-morrow may be a barren prospect; but God is with us; we are near to the Fountain of Life. We often speak of our lack of spiritual life and vigour as though it were a perplexing problem. Is it so, when we do not, will not, drink? There is a “law of the life” of the spirit as well as of the body. Our hearts are like seeds wrapped round so that moisture and air are excluded; such seeds may be planted, but they will not grow. Nor will our hearts wrapped round by prayerlessness, selfishness, indolence, and forgetfulness. Take away these wrappings, lay them aside for ever!
Note further, that this Divine promise pledges God to supply that which is a natural source of verdure, gladness, beauty. This is only one of many instances, in which we are taught that God’s will is not only to preserve, but also to adorn our life (Isaiah 35:1). The young should surely listen to this voice. For them all life is emphatically new; their experiences shall not, indeed, be unparalleled in the history of men, but to them they shall be a new thing from God. Christ declares Himself to be the Giver of “living water;” life, and light, and beauty go before Him; He speaks the word which cannot fail: “Behold, I make all things new!”—Thomas Stephenson: Christian World Pulpit, vol. v. pp. 209–210.
