First of all —it’s all Divine healing— sometimes it’s by the Move of Holy Spirit but as a believer develops in faith and grows in Christ Jesus, he or she can take it.
My definition of Divine Healing verses Faith Healing is that Faith Healing is the individual believer TAKING his or her healing by faith— they themselves, initiate the healing with the understanding of what they have in Christ ( e.g. identity, authority, and what was provided in Death, Burial, Resurrection of Jesus Christ). This is the best way to receive from God across the board for anything.
However, God, like a good daddy who wants to give, fix, restore and make everything good for His children will move even beyond the faith level of a person “MOVED BY COMPASSION” and will heal — especially in a Holy Ghost meeting designated as a Healing service — God will move and a Divine Healing manifests. This is provided by the CORPORATE ANOINTING, which is facilitated by the GENUINE FAITH of Believers. This is why it so utterly important not to forsake the assembling of the Brethren.
