In crisp, unmistakable language, Christ Jesus commanded his followers to "heal the sick, cleanse the lepers, raise the dead, cast out devils."
Not once, but many times, the Master enjoined healing upon his immediate disciples. He rejoiced over the twelve when they returned with fruitage born of obedience to his command.
Christians today generally accept the Biblical record of healings by spiritual means alone as divinely natural for Christ Jesus and his immediate disciples, but not for others. Often the healing work is interpreted as a supernatural gift belonging to a period now past.
