2 Timothy 4:20 note 2
202 Why did the apostle leave in sickness one who was so intimate to him, without exercising healing prayer for him? Why did he not exercise his healing gift (Acts 19:11-12) to cure Timothy of his stomach sickness rather than instruct him to take the natural way for healing (1 Tim. 5:23)? The answer to both questions is that he and his co-workers were under the discipline of the inner life in that time of suffering rather than under the power of the outward gift. The former is a matter of grace in life; the latter is a matter of gift in power—miraculous power. In the decline of the church and in one's suffering for the church, the gift of power is not needed as much as the grace in life.
