In this episode, titled "The Hope of Righteousness by Faith," we saw Paul's aggressive attack on the gospel of works in defence of the gospel of Faith in his letter to the church in Galatia.
We then went on to see that we have the true hope of being justified by Faith (the Spirit), and that through him, we eagerly await the righteousness of Faith (the adoption/redemption/transformation of our lowly body to be conformed to his glorious body), which Paul describes as the manifestation of God's sons in Romans 8.
