Faith is a prerequisite for faith healing, if your faith is not strong enough and the sick has no faith only God can heal the sick. You have to have confidence that your faith has already been tested and measured.
James 5:15 and the PRAYER OF FAITH shall save him that is sick, and the Lord shall raise him up; and if he have committed sins, it shall be forgiven him.
Matthew 9:6 But that you may know that the Son of man had authority on earth to forgive sins (then saith he to the sick of the palsy), Arise, and take up thy bed, and go up unto thy house. God equipped us with self healing.
The four basic elements (sometimes called "temperments") are air, earth, fire, and water. Understanding what each element represents helps us evaluate where our individual strengths and weaknesses are. Healers have found that focusing on the elements can often be helpful when seeking what course of treatments would best address our problems.
