The blessed words: The just shall live by faith appears four
times in the Bible.
First in Habakkuk, then in Romans, in Galatians and in
Hebrews.
In Habakkuk, the immediate context of the words speak of a coming
impending disaster. Particularly an attack by the Chaldeans
[Babylonians] as punishment of the nations long standing
disobedience. These Chaldeans were known for their ruthlessness.
They will ravage and plunder their possessions, their vineyards,
fig tress and other agricultural possessions of the nation. Some
will die, others will suffer and etc. but the just shall live by
faith [faithfulness and integrity]. Thats the primary meaning of
the words as used by Habakkuk.
However, Paul being inspired of God applied these words to
justification by faith and the perseverance of the saints in
Romans, Galatians and Hebrews [for I believe that Paul was the one
wrote Hebrews].
Ro 1:16 For I am not ashamed of the gospel of Christ, for it is the
power of God to salvation for everyone who believes, for the Jew
first and also for the Greek.
17 For in it the righteousness of God is revealed from faith to
faith; as it is written, "The just shall live by faith."
Ga 3:0 For as many as are of the works of the law are under the
curse; for it is written, "Cursed is everyone who does not continue
in all things which are written in the book of the law, to do
them."
11 But that no one is justified by the law in the sight of God is
evident, for "the just shall live by faith."
Heb 10:35 Therefore do not cast away your confidence, which has
great reward.
36 For you have need of endurance, so that after you have done the
will of God, you may receive the promise:
37 "For yet a little while, And He who is coming will come and will
not tarry.
38 Now the just shall live by faith; But if anyone draws back, My
soul has no pleasure in him."
39 But we are not of those who draw back to perdition, but of those
who believe to the saving of the soul.
