It is inappropriate, then, to suggest that God’s gift of the Messiah, if the gift is accepted and subsequently held, would be ineffective in bringing about God’s transformative aims. So we should not set grace at odds with the required behavioral changes (good deeds) associated with allegiant union to Jesus the king.

In short, we cannot say in an unqualified fashion that final salvation is by grace and by faith apart from embodied obedience, for this misunderstands the nature of both charis (“grace”) and pistis (“faith”) in antiquity and in Paul’s Letters.

Question: If we are saved by allegiance alone, and allegiance involves concrete acts of obedience to Jesus the king, then does this not violate the principle that we are saved by faith, not by works? 

Regarding the role of works in salvation, although many systematic treatments attempt to skate around this issue in a variety of ingenious ways, Paul himself states that we will be judged on the basis of our deeds [Romans 2:5-8].
