Which concept is emphasized by the phrase "The just shall live by faith"?

The phrase "The just shall live by faith" emphasizes the concept of faith as a personal journey. This expression highlights the individual's relationship with God and underscores a belief that a just person—those who are considered righteous or in right standing with God—places their trust in Him and leads their life based on that faith. It signifies a continual, personal reliance on God's promises and grace, rather than merely adhering to laws or community traditions.
