Paul, Theology, and Ethics,

“Theology and ethics are intertwined in Paul’s thought for good reason: salvation involves both, not just one or the other, and Christology provides a pattern for Christian behavior, and righteousness and holiness define both the character of God and the intended character of his people. To be an image bearer, one must clothe oneself with Christlike behavior and become an image wearer.”
