Four times we are told in scripture that “the just shall live by faith.” Faith on the finished work of Jesus Christ as our one and only true sacrifice.
Behold the proud, His soul is not upright in him; But the just shall live by his faith. (Hab 2:4 NKJV)
For in it the righteousness of God is revealed from faith to faith; as it is written, “The just shall live by faith. (Rom 1:17 NKJV)
But that no one is justified by the law in the sight of God is evident, for “the just shall live by faith. (Gal 3:11 NKJV)
Now the just shall live by faith; But if anyone draws back, My soul has no pleasure in him. (Heb 10:38 NKJV)
