Basic Theological Framework - Healing Ministry

1. The healing ministry of the Church is based on Jesus' commission to His disciples to preach the gospel, heal the sick and cast out demons (Matt 10:1,7-8, Mark 6:7-12, Luke 9:1-6). The healing of the sick and casting out of demons are to be done in the context of preaching the Gospel. Evangelism and disciple making is the central mission of the Church and the healing/deliverance ministry is subservient to this central task (Matt 28:18-19, Fuller Seminary Faculty's View).
2. Christ's atonement provides us with forgiveness, healing and wholeness (1 Pet 2:24). Ultimately, when Jesus Christ is fully enthroned in His Kingdom, there will be total healing of all spiritual, psychological and physical ailments (Rev 21:4, 22:2, Is 11:1-10). However, because the Kingdom of God is not fully established on earth as yet, we are not entitled to the full benefit of this atonement today (Ken Blue).
3. God's Kingdom had been ushered into the world when Jesus came the first time to die for our sins (Mark 1:15). However this Kingdom has not fully been established on this earth as yet. (The theological concept of God's Kingdom as "already here but not yet fully established"). As a token of His Kingdom invading our world, God still heals today (Matt 10:7-8, Luke 11:20). Yet this healing is not total or fully available until such time when the fullness of His Kingdom comes (Blue).
4. God has called us to pray for the sick and endowed us with all His spiritual gifts to minister to the sick and hurting (Fuller Faculty). It is our responsibility to pray for the sick and it is God's prerogative to heal them. In praying for them, we must fully allow God to do what He thinks best for the counselees - that is, we pray not according to our agenda but to His will (Harold Taylor).
5. The biblical understanding of wholeness and healing covers not only physical, psychological, emotional and spiritual healings, it also includes the restoration of the supplicants' relationships with God and with their community. Our healing must therefore be holistic, touching every aspect of the counselees' life (Robert Hillman).
6. The aim of our healing ministry is not so much as to heal an ailment but to draw people closer to God. Hence, by this definition, the success of our ministry is not measured by the degree of improvement of the sickness but by the extent to which the supplicants experience God in meeting their needs (Leo Thomas).
7. Demons are real and active in our world, and they constantly attack Christians through Satan's strategies of temptations, deceptions and false accusations. Believers can be demonized through their own sinful lifestyle or those of their ungodly ancestors (Neil Anderson).
8. Not all illnesses or human problems are caused or aggravated by demons (Hillman). For those ailments originated or aggravated by evil spirits, deliverance is the right approach to healing. For sicknesses caused by other natural or human factors, different approaches such as prayers for repentance, inner healing, and intercession of faith should be used (Francis MacNutt).
9. We should use both natural and supernatural remedies in our healing ministry. Natural remedies such as encouraging counselees to go for medicine, surgery, secular counseling, healthy diet, and clean living are just as important for healing as supernatural remedies like praying, repenting, forgiving and deliverance (Leo Thomas).
10. Some sick and hurting people are not healed from their ailments after ministry (because the full benefits of Christ's atonement are not yet available to us today). Counselors will do well to teach them that God is not rejecting them but is calling them to endure their suffering with hope and courage while they await their ultimate wholeness (when the fullness of God's Kingdom comes). There is a redemptive value in sickness, pain and suffering as these afflictions often draw us closer to God (Fuller Faculty).
11. It is crucial to follow up counselees over an agreed period of time even after they have experienced healing and restoration. The aftercare phase gives us space to teach and disciple them on how to walk in God's way and live a wholesome lifestyle. It is often important for counselees to maintain their healing/freedom through holy and healthy living (Thomas).
