You are justified in God’s sight not because of what you have done, but only by what Christ has done for you, and imputed to you by God’s free grace.
1. By God’s Free Grace—It doesn’t matter if you are a Jew or a Gentile, all are justified by grace through faith in Christ. Justification is, in God’s Court, your being declared righteous. If our righteousness is filthy rags, then justification by God is a gift.
2. He Pardons All Our Sins—In the case of your standing before the Lord, it is impossible to plead innocence. If you only ever committed the least sin, you stand condemned by the Law, because it is holy, good and demands perfection from you. Your heart is sinful and wicked, so every good thing you do is marred by your own self-seeking interests. These acts come from a state of sin. They cannot prove that you are righteous, because you are not so in and of yourself. They only prove your unrighteousness. But the Bible says that those who repent of their sins and believe will receive a pardon.
3. He Accepts Us as Righteous in His Sight—When you are justified, Jesus Christ’s righteousness is imputed to you. The holy God chose to love elect sinners and so imputes his Son’s righteousness to them.
