If then what we see not, etc. This is an argument derived from what the antecedent implies; for patience necessarily follows hope. For when it is grievous to be without the good you may desire, unless you sustain and comfort yourselves with patience, you must necessarily faint through despair. Hope then ever draws patience with it. Thus it is a most apt conclusion -- that whatever the gospel promises respecting the glory of the resurrection, vanishes away, except we spend our present life in patiently bearing the cross and tribulations. For if life be invisible, we must have death before our eyes: if glory be invisible, then our present state is that of degradation. And hence if you wish to include in a few words the meaning of the whole passage, arrange Paul's arguments in this way, "To all the godly there is salvation laid up in hope; it is the character of hope to look forward to future and absent benefits: then the salvation of the faithful is not visible. Now hope is not otherwise sustained than by patience; then the salvation of the faithful is not to be consummated except by patience." It may be added, that we have here a remarkable passage, which shows, that patience is an inseparable companion of faith; and the reason of this is evident, for when we console ourselves with the hope of a better condition, the feeling of our present miseries is softened and mitigated, so that they are borne with less difficulty.

1 - "Patience," says Pareus, "is needful for three reasons, -- the good expected is absent, -- there is delay, -- and many difficulties intervene." -- Ed.

But if we hope - The effect here stated is one which exists everywhere. Where there is a strong desire for an object, and a corresponding expectation of obtaining it - which constitutes true hope - then we can wait for it with patience. Where there is a strong desire without a corresponding expectation of obtaining it, there is impatience. As the Christian has a strong desire of future glory, and as he has an expectation of obtaining it just in proportion to that desire, it follows that he may bear trials and persecutions patiently in the hope of his future deliverance. Compared with our future glory, our present sufferings are light, and but for a moment; 2-Corinthians 4:17. In the hope of that blessed eternity which is before him, the Christian can endure the severest trial, and bear the intensest pain without a complaint.

But if we hope for that we see not - If we have a well-grounded expectation of our resurrection and final glorification, knowing that such things are necessarily future, and must for a certain time be delayed; then do we patiently wait for them, continue patiently to endure the common ills of life, and whatever tribulations we may be exposed to in consequence of our Christian profession; for we know, Faithful is he who has promised. Hope is a sort of universal blessing, and one of the greatest which God has granted to man. To mankind, in general, life would be intolerable without it; and it is as necessary as faith is even to the followers of God.
The ancients have a very instructive and elegant fable concerning it. "Prometheus having made a human body, went up to heaven, and stole some celestial fire to animate it: Jupiter, incensed at the theft, sent down Pandora, with a box full of diseases and plagues of every kind, as an ensnaring present to Prometheus; but he refused to accept it. Epimetheus took and opened it, and instantly all those diseases, etc., by which mankind have been made miserable, flew out, and spread themselves over the whole earth; and only Hope remained at the bottom of the box." This fable explains itself, as to its main design. Men find life, with its various and unavoidable ills, only supportable by the hope they have of not only getting safely through them, but of enjoying a state of blessedness in the end. Hope is still at the bottom; and therefore man is encouraged to bear up in all the pressures of life. Take away hope, and then black despair and indescribable wretchedness would be the instant result. Hope stands justly among the highest mercies of God.

But if we hope for that we see not,.... Whether it be the hour of death, or the second coming of Christ, or the resurrection of the dead, and eternal glory; all which are unseen by us, and to be hoped for:
then do we with patience wait for it; as that which is certain and real, as something valuable, which will be satisfying, and be received with the utmost joy. This supposes, that the persons who wait for it believe it, and their interest in it, at least hope they have one; that they have a valuable esteem and affection for it; that they are not in a state of perfection and happiness; and that they sit loose by the things of this world, and are ready to part with the one, and grasp the other: the manner of their waiting is "with patience"; a grace, of which God is the efficient, Christ is the exemplar, and the word the means; and which is of great use under afflictions from the hand of God, under the reproaches and persecutions of men, under desertions and want of answers in prayer, under the temptations of Satan, and in the expectation of the heavenly glory.

But if we hope for that we see not, then do we with patience wait for it--that is, then, patient waiting for it is our fitting attitude.
