3. This vision, the accomplishment of which is so long waited for, will be such an exercise of faith and patience as will try and discover men what they are, v. 4. (1.) There are some who will proudly disdain this vision, whose hearts are so lifted up that they scorn to take notice of it; if God will work for them immediately, they will thank him, but they will not give him credit; their hearts are lifted up towards vanity, and, since God puts them off, they will shift for themselves and not be beholden to him; they think their own hands sufficient for them, and God's promise is to them an insignificant thing. That man's soul that is thus lifted up is not upright in him; it is not right with God, is not as it should be. Those that either distrust or despise God's all-sufficiency will not walk uprightly with him, Gen. xvii. 1. But, (2.) Those who are truly good, and whose hearts are upright with God, will value the promise, and venture their all upon it; and, in confidence of the truth of it, will keep close to God and duty in the most difficult trying times, and will then live comfortably in communion with God, dependence on him, and expectation of him. The just shall live by faith; during the captivity good people shall support themselves, and live comfortably, by faith in these precious promises, while the performance of them is deferred. The just shall live by his faith, by that faith which he acts upon the word of God. This is quoted in the New Testament (Rom. i. 17; Gal. iii. 11; Heb. x. 38), for the proof of the great doctrine of justification by faith only and of the influence which the grace of faith has upon the Christian life. Those that are made just by faith shall live, shall be happy here and for ever; while they are here, they live by it; when they come to heaven faith shall be swallowed up in vision.
