As Paul argues, it is the righteousness of God that is revealed in the law, and this condemns us all (Ro 1:18 - 3:20), while the gospel reveals the righteousness from God, namely, that we "are justified by his grace as a gift, through the redemption that is in Christ Jesus" (Ro 3:24).

Michael HortonA church that is deeply aware of it's misery and nakedness before a holy God will cling tenaciously to an all sufficient Savior, while one that is self-confident and relatively unaware of its inherent sinfulness will reach for religion and morality whenever it seems convenient
Michael HortonThe object is evident in the name of the discipline. Similarly, theology (theologia) is the study of God. The object of theology is not the church's teaching or the experience of pious souls. It is not a subset of ethics, religious studies, cultural anthropology, or psychology. God is the object of this discipline.
