Hebrews 10:38

“"...the righteous person will live by his faithfulness—”

Quoted in Hebrews 10:38; key concept of living by faith.

“For in the gospel the righteousness of God is revealed—a righteousness that is by faith from first to last, just as it is written: “The righteous will live by faith.””

Echoes Habakkuk 2:4, emphasizing faith as the basis of righteousness and life.

“Clearly no one who relies on the law is justified before God, because “the righteous will live by faith.””

Quotes Habakkuk 2:4, contrasting faith with reliance on the law.

“If they have escaped the corruption of the world by knowing our Lord and Savior Jesus Christ and are again entangled in it and are overcome, they are worse off at the end than they were at the beginning. It would have been better for them not to have known the way of righteousness, than to have known it and then to turn their backs on the sacred command that was passed on to them. Of them the proverbs are true: “A dog returns to its vomit,” and, “A sow that is washed returns to her wallowing in the mud.””

Illustrates the danger of drawing back after professing faith.

“It is impossible for those who have once been enlightened, who have tasted the heavenly gift, who have shared in the Holy Spirit, who have tasted the goodness of the word of God and the powers of the coming age and who have fallen away, to be brought back to repentance.”

Warns against apostasy and the impossibility of renewal for those who fall away.
