Righteousness is not just being right, or merely instruction from God and obeying it. Righteousness is revealed from faith to faith which is progression in truth. The Holy Ghost reproves the world of righteousness because JESUS goes to the Father, being glorified with the Father's own self. New believers as newborn babes are unskillful in the word of righteousness. Know JESUS is Jehovah-tsidkenu; the LORD Jehovah-tsidkenu our righteousness.
