How do we know the just shall live by faith is true?

The declaration that 'the just shall live by faith' is a foundational truth found in Habakkuk 2:4 and reiterated in Romans 1:17 and Galatians 3:11. This verse underscores that true life for the justified is found in faith, which itself is a gift from God (Ephesians 2:8-9). Living by faith means that believers look to Christ alone for their righteousness and hope, trusting in His grace rather than their own works or merit. This principle is integral to understanding salvation; as Romans 4:5 states, it is to the one who does not work but believes in Him who justifies the ungodly that his faith is counted as righteousness. Thus, the faith of the just is not a single act but a continual reliance on Christ.
