Righteousness is the nature of God that's imparted to the human spirit, producing in him the rightness of God and the ability to do right and fulfil the will of the Father. God is always right; that's His nature, and He has produced that same nature in us. You don't have to read the entire Book of the Law and its ordinances to know what's right or wrong: the righteousness of God has been imparted to your spirit.
In the days of Moses, the Israelities had to read the Law to know right or wrong; but that's not for the new creation in Christ! In Jeremiah 31:33, the Lord said, "....I will put my law in their inward parts, and write it in their hearts..." This is what has happened; righteousness is now in your spirit. Romans 8:3-4 tells us, "For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh: That the righteousness of the law might be fulfilled in us..."
The law of the Spirit of life in Christ Jesus has produced righteousness in your spirit. No wonder Jesus said, "Ye are the light of the world..." (Mathew 5:14); you are to look at you, and know what rightness is. You're not only a partaker, but the expression of His righteousness. Isaiah 61:3 calls us trees of righteousness; the planting of the Lord of Hosts, that He might be glorified. Therefore, you bear fruits of righteousness ( Phillipians 1:11).
Let righteousness reign through you; give expression to God's best in your life. Decide that the life of Christ will be expressed through you fully, and that you'll be effective in propagating the Gospel. Make up your mind on it, and it shall be so.
