Brother Brown seemed to be very slow about learning that the Lord required the missionaries engaged in his ministry to use wisdom in the matter of conserving their health, to avoid undue exposure, the drinking of impure or contaminated water, going heedlessly in the way of epidemics, etc. While the Lord has the power to heal them, and they, being in His service, should have a special claim upon His protection and blessing, they should not knowingly "tempt the Lord." The account given us in the Bible of Satan taking the Savior up on to the pinnacle of the Temple and proposing that he cast Himself down, may serve as an illustration of the principle under consideration. Of course, the Father had it in His power to save Him, but the injunction was, "Thou shalt not tempt the Lord thy God." In the ordinary nature of things certain penalties follow the breaking of certain laws. One of the laws of nature is that the human body is incapable of enduring an intense heat. If it comes in contact with fire the flesh is burned, and pain and suffering and perhaps dissolution follows. Of course, the Almighty is able to arrest the operation of a law of nature, as He did in the case of the three Hebrew children that the Bible tells us of being cast into the fiery furnace, but there was special reason for His doing so in their case. They were in the line of their duty, and it was because of their devotion to His cause that they were cast into the furnace, and there was therefore more reason for the Lord coming to their rescue than there would have been had they voluntarily gone into the fire, and thus "tempted the Lord" to suffer them to be destroyed. Every missionary owes it to himself, to his family, to the people among whom he is sent to labor and to the cause he represents, to take good care of his health, to consider differences in climate, and food, and water and altitude, any or all of which may affect him injuriously unless great care be exercised on his part until he become acclimated or accustomed thereto.
