The biblical framework for healing makes it clear that the most important dimension of healing is not physical – although this aspect is certainly important – but rather the spiritual restoration of our relationship with God. This work of grace in Christ through the Spirit overcomes our alienation and brings us into a dynamic relationship with the Trinity.
Thus salvation is healing, and the initial movement of this healing is homecoming, which is expressed beautifully in Paul's vision of being welcomed into God's covenant of grace (Ephesians 2.11-14). The ongoing movement of this restorative healing continues as we grow into Christian maturity and the graces and virtues of the Christian life (Galatians 5.22-23) and also in conformity to Christ and his way of being in the world (Ephesians 4.13). When our greatest hurt is healed, we experience God's salvation in Christ. Thus the word of grace has healing power . . . The gospel is medicine, indeed. (Extract from: Charles Ringma & Mary Dickau.
