ROMANS 5:1 NLT 1 Therefore, since we have been made right in God’s sight by faith, we have peace with God because of what Jesus Christ our Lord has done for us.
God offers righteousness as a free gift to everyone who receives the Lord Jesus Christ.
Righteousness means right-wise-ness, or being right. So righteousness is right standing, or good standing with God. It does not mean human “perfection.”
Righteousness is a gift from God — not something you can earn or achieve. God simply declares that you are innocent, as far as He is concerned, because you believe in Jesus, and that makes you righteous.
1 CORINTHIANS 1:30 NKJ 30 But of Him you are in Christ Jesus, who became for us wisdom from God — and righteousness and sanctification and redemption
You ARE righteous if Jesus is your Lord. In fact, Jesus IS your righteousness. As a believer in Jesus, you will never be more righteous — no matter what you do.
Romans 3:10 is a well known verse on this subject that is often misunderstood. It is a quote from the Old Testament, and is part of a passage that continues on to say that NOW we can be righteous through faith in Jesus Christ.
ROMANS 3:10 NKJ 10 As it is written: “There is none righteous, no, not one;

Romans 10 gives instructions on how to become righteous.
ROMANS 10:9-10 NKJ 9 that if you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved. 10 For with the heart one believes to righteousness, and with the mouth confession is made to salvation.
