Where does the concept of justification come from in the Bible?

The concept of justification is derived from God’s action of declaring sinners righteous based on their faith in Christ. In Isaiah 45:25, the promise that the seed of Israel shall be justified reveals God’s commitment to save His people. This theme continues through the New Testament, particularly in Romans 5:1, where Paul states that we are justified by faith. Justification is not based on personal merit or works but rather on the imputed righteousness of Christ, as explained in 2 Corinthians 5:21, where God made Christ to be sin for us so we could be made righteous. This exchange forms the heart of the gospel and highlights the beauty of God’s justice and grace.
