[Sickness and infirmity are often sent as preventives, as well as for chastening. "Lest I should be exalted above measure . . . there was given to me a thorn in the flesh, the messenger of Satan to buffet me." (2 Cor. 12:7.) How much Paul owed to that thorn in the flesh, who can tell ? With it also he had the assurance, " My grace is sufficient for thee:for my strength is made perfect in weakness." Let us seek ever to be exercised by what the Lord sends upon us, rather than to get out of it as easily as possible.
