Psalm 37:6

"He will bring forth your righteousness as the light, and your justice as the noonday."

Since Christ sacrificed Himself for us, and since we no longer live, but rather Christ lives in us, the righteousness and justice we may have is not even our own. God counts them as our own, but they originated from Jesus Christ. Through the power of the Holy Spirit and true faith in Christ (delighting yourself in God, committing your way to Him, etc.), God will show off this righteousness in us, and all of the glory goes back to Him. It's all about Him.

Peace.
