In sum, although the experience of purity helps us understand morality, the metaphorical connection between the two is so deep that the experience of physical purity can come to replace moral action. And, given that the church is awash in purity metaphors, particularly those churches who privilege penal substitutionary thinking, there exists a constant danger that the church will exchange the private experience of salvation, being washed in the blood of the Lamb, for passionate missional engagement with the world.
