What does the Bible say about the effect of righteousness?

Isaiah 32:17 explicitly tells us that the work of righteousness shall be peace, and the effect of righteousness is quietness and assurance forever. This means that righteousness is not just a concept but has tangible effects in the lives of believers. When Christ, who is our righteousness, reigns, He brings about an inner peace that resolves fears and anxieties. The assurance that comes from righteousness grants us a confidence that is eternal, rooted in the completed work of Christ, which is the foundation of our faith and hope.
