"The righteousness of God is what God does;
--it is His way.
--To be in harmony with Him is to make His way our way.
The gospel reveals this way to us (For therein is the righteousness 
of God revealed from faith to faith: as it is written, The just shall live by faith. Romans 1:17), and not only this but it is the power of God to work out His way in us.
The Bible is a statement of God's way, and this is summed up in the ten commandments, which are a declaration of His righteousness. (Hearken unto me, ye that know righteousness, the people in whose heart is my law; .. Isaiah 51:7)."
