For about 40 years I have heard believers state, “the just shall live by faith.” For that whole time I have taken that to mean, that by their faith, or following their faith, they will live on this earth. That is, we follow the blueprint that God laid down in the Bible for us to live by, not by law but by faith. The focus being on the living by faith, trusting in the living God. That view seems to be supported by these New Testament Scriptures:
Hebrews 10:38 Now the just shall live by faith: but if any man draw back, my soul shall have no pleasure in him.
Galatians 3:11 But that no man is justified by the law in the sight of God, it is evident: for, The just shall live by faith.
Romans 1:17 For therein is the righteousness of God revealed from faith to faith: as it is written, The just shall live by faith.
I understand when Paul wrote in Romans 1:17 “it is written” he was quoting from the Old Testament Scriptures.
