Isaiah 40:1-31 · Part 4

That Jehovah is the God of eternity. The Prophet calls him “eternal,” and thus distinguishes him from all idols, which endure but for a time, and were made by men; and truly, if this were deeply seated in our hearts, there would no longer be any room for distrust; for if God is eternal, he never changes or decays, eternity being uniformly attended by this quality, that it is never liable to change, but always remains the same. Since the Jews did not sufficiently believe these things, though they had often “heard” them, the Prophet intended to arouse them by this reproof, in order to shew that they will be doubly guilty before God, if, after having been taught both by his numerous benefits, and by the word, they do not render the honor and glory which are due to him.

And is not wearied by weariness, and there is no searching of his understanding. Here the Prophet makes two statements; first, that God is not wearied in doing good; and, secondly, that no man can explore his wisdom. In the former clause he shews that, nothing will hinder God from continuing to exercise his kindness; for he is not like men whose resources are exhausted by giving frequently, or who are wearied by continually bestowing new favors, or who repent of their generosity. His kindness is never exhausted; if he was kind to the fathers, he will be not less kind and bountiful to posterity. As to the allegation, that God very often acts differently from what we think to be best for us, the Prophet meets it by saying that his purpose is incomprehensible, and warns us that we ought not to murmur, though he does not all at once comply with our wishes; because nothing is better adapted to cherish our hope than this sobriety, which leads us to consider how marvellously God works in preserving us, and thus to submit to his secret counsel.

29. He giveth power to the faint. The Prophet now applies to the present subject the general statements which he made; for we have said that his intention was to give warmer encouragement to the people, and to lead them to cherish better hope. Because the Jews were at that time weakened and destitute of all strength, he shews that on this account it belongs to God to give assistance to those who were thus exhausted and weakened. He therefore magnifies the power of God on this ground, that they may conclude and believe that they ought not to doubt of their salvation so long as they enjoy his favor. It was indeed to the people who were held captive in Babylon that the Prophet looked; but we ought also to apply this doctrine to ourselves, that whenever our strength shall fail, and we shall be almost laid low, we may call to remembrance that the Lord stretches out his hand “to the faint,” who are sinking through the want of all help. But first, we must feel our faintness and poverty, that the saying of Paul, “The power of God is made perfect in our weakness,” (2 Corinthians 12:9,) may be fulfilled; for if our hearts are not deeply moved by a conviction of our weakness, we cannot receive seasonable assistance from God.

30. The youths are wearied and faint. By this comparison the Prophet illustrates more powerfully what he had formerly said, that the strength which God imparts to his elect is invincible and unwearied; for men’s strength easily fails, but God’s strength never fails. It is indeed certain that all the vigor which naturally dwells in us proceeds from God; but since men claim as their own what God has bestowed generally on all, the Prophet thus distinguishes between the strength of men which appears to be born with them, and that strength by which God peculiarly supports his elect; for God’s kindness, which is diffused throughout all nature, is not sufficiently perceived. And thus by “men’s strength” he means that which is generally possessed by mankind, and by “God’s assistance,” he means that by which he peculiarly assists us after our strength has failed; for the Prophet speaks of the grace of God which is cormmonly called supernatural, and says that it is perpetual, while men can have nothing in themselves but what is fading and transitory; that by this mark he may distinguish between the Church of God and the rest of the world, and between spiritual grace and earthly prosperity.

And the young men by falling fall. In the former clause he made use of the word נערים, (negnarim,) youths, but now he adds בחרים, (bachurim,) which means not only that they were “young men,” but also that they had been selected. The repetition of the same statement may be supposed to refer particularly to age, though he means that they were persons of the choicest vigor and in the prime of life. With this design he recommends that excellent privilege which God bestows on his children in preference to other men; that they may be satisfied with their lot, and may bear no envy to earthly men, for that strength of which they boast. In a word, he shews that men are greatly deceived if they are puffed up by confidence in their own strength, for they immediately sink and faint.

He appears to allude to what happens every day, that the stronger any person is, the more boldly does he attempt what is exceedingly difficult, and the consequence is, that they who are naturally more robust seldom live to be old men. They think nothing too hard or difficult, they attempt everything, and rashly encounter all dangers; but they give way in the middle of their course, and suffer the punishment of their rashness. The same thing befalls those who are proud of any gift which God has bestowed on them, and are full of confidence in themselves; for all that they have received from God is reduced to nothing, or rather turns to their ruin and destruction; and thus they are justly punished for their insolence.

31. But they that wait for Jehovah. Hebrew writers employ the phrase, “exchanging strength,” to denote “gathering new strength,” and thus “being restored.” The Prophet therefore shews, that godly persons, who shall hope in God, will not be deficient in strength; and he confirms what he formerly said,

“In rest and silence shall be your strength.” (Isaiah 30:15.)

We must not become agitated, or throw ourselves forward rashly, but “wait” patiently. In this passage, therefore, waiting means nothing else than patience. Violent men dash themselves to pieces by their own eagerness, but the vigor of godly men, though it has less display, and often appears to lie buried while they calmly “wait for” God’s assistance, is refreshed and renewed. We must therefore return to the saying of Paul, that

“the power of God is made perfect in our weakness.” (2 Corinthians 12:9.)

We must, therefore be fully convinced of our weakness, that we may yield to the power of God. The Jews, who were oppressed by that cruel captivity, had great need of this doctrine; but for us also, during this wretchedly ruinous condition of the Church, it is exceedingly needful.

They shall raise their wings as eagles. It is generally believed that the Prophet uses this phrase in the same sense that the Psalmist says,

“Thy youth shall be renewed like that of the eagle.” (Psalm 103:5.)

It is certain that the “eagle” is very long-lived as compared with other birds.

Aristotle and Pliny affirm that it never dies of old age, but of hunger; that is, that when the upper part of the beak becomes too large, it cannot take food into its mouth, and for a long time subsists entirely on what it drinks. One Zaadias, as all Jews are audacious in constructing fables, pretends that the eagle flies upward into the region that is near the sun, and approaches the sun so closely, that its old wings are burned, and other new ones grow in their place; but this is utterly absurd and fabulous. The Prophet means that they who trust in the Lord will be vigorous, like eagles, till the most advanced old age. But seeing that eagles fly higher than other birds, by which they shew remarkable swiftness, which has also given rise to the proverb, “An eagle among the clouds,” this passage may be understood to denote not only long life, but also strength and agility; so that Isaiah, after having shewn that their strength is recruited, adds that they are more vigorous, and ascend to a great height. Such is also the import of what follows, —

They shall run and shall not be weary. It is as if he had said, that the Lord will assist them, so that they shall pursue their course without any molestation. It is a figurative expression, by which he intimates that believers will always be ready to perform their duty with cheerfulness. But it will be said, “There are so many troubles which we must endure in this life; how then does he say that we shall be exempt from weariness?” I reply, believers are indeed distressed and wearied, but they are at length delivered from their distresses, and feel that they have been restored by the power of God; for it happens to them according to the saying of Paul,

“While we are troubled on every side, we are not overwhelmed; we are perplexed, but are not in despair; we suffer persecution, but are not forsaken; we are cast down, but are not destroyed.” (2 Corinthians 4:8, 9.)

Let us therefore learn to flee to the Lord, who, after we have encountered many storms, will at length conduct us to the harbor; for he who hath opened up a path, and hath commanded us to advance in that course in which he hath placed us, does not intend to assist us only for a single day, and to forsake us in the middle of our course, (Philippians 1:6,) but will conduct us to the goal.
