1. Self-Righteous: The bible defines self-righteousness as relying on one's own merits of righteousness as the grounds for their salvation and the reason for God to save them.
2. Righteous of Christ Jesus: Romans 3:20-31 We are justified through faith in the sacrifice of Jesus Christ. He is the payment for our sins, thus freeing us from sin's penalty, and at the same time, God accounts—or imputes—Christ's righteousness to us.
You don't decide when you are holy and righteous, because you can't earn it. The Bible describes the Sadducees as self-righteous, and self-righteousness is actually just being full of yourself. The Bible says to boast in nothing. Salvation is a gift from God.
What does it mean to be the righteousness of God in Christ Jesus? It simply means that when God looks at us, He sees us through Jesus Christ and His finished work of the cross. We are completely accepted by God and are clothed with Jesus robes of righteousness.
Hebrews 9:14 How much more, then, will the blood of Christ, who through the eternal Spirit offered himself unblemished to God, cleanse our consciences from acts that lead to death, so that we may serve the living God!
Romans 2:13For it is not those who hear the law who are righteous in God’s sight, but it is those who obey the law who will be declared righteous.
2 Corinthians 5:18-20 All this is from God, who reconciled us to himself through Christ and gave us the ministry of reconciliation: that God was reconciling the world to himself in Christ, not counting people’s sins against them. And he has committed to us the message of reconciliation. We are therefore Christ’s ambassadors, as though God were making his appeal through us. We implore you on Christ’s behalf: Be reconciled to God.
1 Peter 3:8-18 Finally, all of you, be like-minded, be sympathetic, love one another, be compassionate and humble. Do not repay evil with evil or insult with insult. On the contrary, repay evil with blessing, because to this you were called so that you may inherit a blessing. For, “Whoever would love life and see good days must keep their tongue from evil and their lips from deceitful speech. They must turn from evil and do good; they must seek peace and pursue it. For the eyes of the Lord are on the righteous and his ears are attentive to their prayer, but the face of the Lord is against those who do evil.” Who is going to harm you if you are eager to do good? But even if you should suffer for what is right, you are blessed. “Do not fear their threats; do not be frightened.” But in your hearts revere Christ as Lord. Always be prepared to give an answer to everyone who asks you to give the reason for the hope that you have. But do this with gentleness and respect, keeping a clear conscience, so that those who speak maliciously against your good behavior in Christ may be ashamed of their slander. For it is better, if it is God’s will, to suffer for doing good than for doing evil. For Christ also suffered once for sins, the righteous for the unrighteous, to bring you to God. He was put to death in the body but made alive in the Spirit.
