Some features of Pent. doctrine of healing: 1/ it links healing of the body to the work of Christ, which makes the most sense in a framework where salvation concerns healing the soul&body & overcoming the 'powers' against humanity (sin,death,devil). https://twitter.com/JanEngleLewis1/status/1346119020857081866
2/ it assumes fundamental connection&relation b/w body&soul in humanity. In this sense, it's related to resurrection&ascension. It also presupposes the link b/w physiological phen. (like bodily appetites) & psychological phen. (like emotions).
3/ It places the healing of the body in the context of sanctification since holiness was partly about ritual purity connected to a wholeness of life. Thus, to pray for physical healing is to pray that God sanctify the person. This is to pray for deliverance from infirmity.
4/B/c of the relation b/w physiology&psychology, the doctrine presumes that prayers to "conquer" depression involve petitions for physical healing&cooperation w/the Spirit to cure the soul of disordered emotion&desire. It's always both/and.
5/b/c it's part of establishment of kingdom, physical healing (like healing of cosmos) is a process punctuated by transforming moments culminating in new body/earth/heaven. This eschatological orientation means healing isn't always immediate b/c it's folded into a larger process.
