Quote from : Pilgrim Theology: Core Doctrines for Christian Disciples Book

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).
