For as God, when He brought the Israelites into the Land of Promise, did not secure them therein, by subduing all the nations round about them; but left many of them, as thorns in their sides, to awaken from time to time their piety and industry: so our Saviour, in conducting us toward His heavenly kingdom, did not destroy all the difficulties of natural questions; but left them to exercise our industry and reason; the scope of His preaching being only to show us this plain and direct way to salvation, namely, the belief of this article, “that He was the Christ, the Son of the living God, sent into the world to sacrifice himself for our sins, and at His coming again, gloriously to reign over His elect, and to save them from their enemies eternally.” To which the opinion of possession by spirits, or phantasms, is no impediment in the way; though it be to some an occasion of going out of the way, and to follow their own inventions. If we require of the Scripture an account of all questions which may be raised to trouble us in the performance of God’s commands, we may as well complain of Moses for not having set down the time of the creation of such spirits, as well as of the creation of the earth and sea, and of men and beasts.
