If you are unsure how to go about healing someone, this is a great read form Bas Rijksen and Communicating Grace:
It deals with amongst other matters:
The Word of God being our final authority; healing in the old covenant versus New Covenant; divine healing as the will of God; clarifying God’s sovereignty and man’s responsibility; traditional sacred Cows standing between us and executing our authority; being led and being anointed; and exercising dominion by healing the sick.
It also contains some appendixes explaining:
- simple aspects to divine healing
- Kingdom laws: God is predictable and His power is mechanical
- Gifts of the Spirit
- What is God’s will?
- Practical pointers to heal anyone, anywhere, anytime
- Speaking the Word
- Questions and answers
