Hebrews 10:38

“Now the just shall live by faith, etc..] The “just” man is one not in appearance only, but in reality; not by his obedience to the law, but by the obedience of Christ; and he is evidently so by the Spirit, and by faith: and he is one, who lives soberly and righteously; and the life he lives, and shall live, at present, is, not eternal life; for though he shall live that life, yet this is not intended; for it is a living by faith that is spoken of, and as antecedent to the coming of Christ; but a spiritual life is meant, a life of justification in Christ, a life of communion with Christ, and a life of holiness from Christ, with peace, joy, and comfort through him: and the manner of this just…”

“just--The oldest manuscripts and Vulgate read, "my just man." God is the speaker: "He who is just in My sight." BENGEL translates, "The just shall live by my faith": answering to the Hebrew, Hab 2:4; literally, "the just shall live by the faith of Him," namely, Christ, the final subject of "the vision," who "will not lie," that is, disappoint. Here not merely the first beginning, as in Gal 3:11, but the continuance, of the spiritual life of the justified man is referred to, as opposed to declension and apostasy. As the justified man receives his first spiritual life by faith, so it is by faith that he shall continue to live (Luk 4:4). The faith meant here is that fully developed living trust…”

“Now the just shall live by faith - This is a part of the quotation from Habakkuk Habakkuk 2:3-4, which was probably commenced in the previous verse; see the passage fully explained in the notes on Romans 1:17. The meaning in the connection in which it stands here, in accordance with the sense in which it was used by Habakkuk, is, that the righteous should live by “continued confidence” in God. They should pass their lives not in doubt, and fear, and trembling apprehension, but in the exercise of a calm trust in God. In this sense it accords with the scope of what the apostle is here saying. He is exhorting the Christians whom he addressed, to perseverance in their religion even in the midst…”

“Now the just - The justified person. Shall live - In God's favour, a spiritual and holy life. By faith - As long as he retains that gift of God. But if he draw back - If he make shipwreck of his faith My soul hath no pleasure in him - That is, I abhor him; I cast him off. Hab 2:3, &c. Hebrews 10:39”
