What does the Bible teach about the righteousness of believers?

The Bible teaches that true righteousness before God is not based on human efforts but solely through faith in Christ. Zacharias and Elizabeth were described as righteous, not because of their works, but because their faith looked forward to the coming Messiah, who would fulfill the law on their behalf. In Romans 8, believers are affirmed to be justified by Christ's obedience. This imputed righteousness means that when God looks at His people, He sees them as guiltless, secured by the sacrifice of Christ. This doctrine underscores the grace of God in salvation and assures believers that their standing is firm based on Christ's merit alone.
