10:39

we are . . . the sort who have faith: With these reassuring words, Paul introduces his vital discussion of the quality of faith and how men and women in the past manifested it. (Heb 11:1–12:3) Although Paul had to give some strong counsel in his letter to the Hebrew Christians, he still expresses heartfelt confidence in them. (Compare study note on Heb 6:9.) His confidence was based on the knowledge that Jehovah, the Source of faith, could help them to follow the example of Jesus, “the Chief Agent and Perfecter” of the faith of each Christian.​—Heb 12:2 and study notes; Eph 2:8.

shrink back: The Greek word rendered “shrink back” may at times refer to hesitancy or timidity. Here, though, Paul does not have in mind the kind of temporary lapse of courage that befell the prophet Elijah or the apostle Peter. (1Ki 19:1-5; Mt 26:69-75; Lu 24:33, 34) Rather, the expression “shrink back” describes a person who develops “a wicked heart lacking faith” and who draws away “from the living God.”​—Heb 3:12 and study notes.

to destruction: This phrase makes clear what awaits those who faithlessly “shrink back” and “practice sin willfully.” (Heb 10:26 and study note, 27) The same Greek word rendered “destruction” was applied to Judas Iscariot. (See study note on Joh 17:12.) A Christian who chooses such a willful course of sin faces Jehovah’s judgment of eternal destruction. In contrast, a Christian who cultivates and exercises faith receives his reward from Jehovah​—the eternal preservation of his life.

lives: Or “souls.”​—See Glossary, “Soul.”
