According to the Cambridge dictionary, a healer is a person who has the power to cure ill people without using ordinary medicines. Note that a Healer heals others from illness or injury, and is not to be confused with Miracles. Modern medical authorities state that a very large percentage of illnesses have a psychosomatic origin, and thus a Healer must always be aware of the healing of underlying issues that may need to be ‘healed’ as Jesus demonstrated in Matthew 9:1-8 with the paralytic.
We often don’t classify Healer as one of the 5 fold ministry gifts, but looking at 1 Cor 12:28 we see the gift of healings described as part of the offices appointed by God to the church. Healers will demonstrate and present the gospel and often bring teachings. These teachings to the body of Christ include the realisation that all people are children of God with the ability and authority to heal the sick as per Mark 16:18. The Healer will encourage and equip people to recognise their gifting and possible office as a healer. Each expression of this office is to fully equip, motivate, train up, teach and enable the saints for the work of the ministry so that they may mutually contribute in their specific function to give definition to the visible body of Christ (Eph. 4:12). A form of apprenticeship will be established by the Office of Healer and those displaying healing gifts, so that their gift is developed to the point where new Officers of Healing will be raised up.
