My understanding of natural healing is that when God created earth, He included in herbs, chemical extracts, and other natural products every cure that we would need for the healing of our bodies. Until the 18th century, these cures were natural products. Then scientists learned to compose chemical equivalents to natural things. Medicines then became more readily available to the general public. No doubt some chemicals have been misused, but on the whole they’ve been beneficial.
God’s healing power is different, in that it is not based on either natural or chemical remedies but is supernatural: above and beyond things natural. Some Christians in times past railed against medicine and doctors, as if they were from Satan himself. Some early Pentecostal tent evangelists were very much against doctors and medicine. I understand why: they were ‘breakthrough’ preachers and were persecuted — a few were jailed — for their extremist views.
But the view held by those preachers that medicines beneficial to mankind were satanic in their origin was absurd, given his totally destructive nature and desire to ruin the crowning glory of God’s creation. Moreover, the human body itself contains physiological properties and repellents that aid recovery from internal and external diseases. When some kind of dysfunction takes place, other parts are known to ‘take up the slack’ so that the body is able to continue to function.
Thank God for doctors, for surgeons, and for medical diagnoses, prognosis and prescriptions; but thank God most of all for the overriding authority and ability of Jesus Christ our Lord to heal our bodies, and his willingness to do so — as proven in the ministry of our Lord Jesus Christ, who spent about two-thirds (66%) of his time on earth healing the sick! And has continued to do so ever since! God is my first resort but I do have a doctor for check-ups, blood tests, and prescriptions. I never accepted the needle for Covid-19 and I do not for influenza; but I do believe in preventive inoculations against basic diseases for children and others who need them.
Jesus said: “For I always do those things that please [the Father].” (John 8:29) See also John 4:34; John 5:30 & John 6:38. I do not have all the answers but I rest in my belief that God does.
