Next to Satan’s deceits in tempting to sin and against duty, his design of _corrupting the minds of men by error_ calls for our search; and indeed this is one of his principal endeavours, which takes up a considerable part of his time and diligence. He is not only called in Scripture an ‘unclean spirit,’ but also a ‘lying spirit,’ [1 Kings xxii. 22,] and there are none of these cursed qualifications that lie idle in him. As by his uncleanness we may easily conjecture his attempts upon the will and affections to defile them by lust; so by his lying we may conclude that he will certainly strive to blind the understanding by error. But a clear discovery of this we may have from these considerations:— I. 1. First, _From God’s interest in truth, in reference to his great designs of holiness and mercy in the world_. Truth is a ray and beam of him who is the Father of lights.[210] All revealed truths are but copies and transcripts of that essential, archetypal truth. Truth is the rod of his strength, Ps. cx. 2, the sceptre of his kingdom, by which he doth subdue the hearts of men to his obedience and service in conversion. Truth is that rock upon which he hath built his church, the foundations are the prophets and apostles, Eph. ii. 20—that is, the doctrine of the prophets and apostles, in the Scriptures of the Old and New Testament. Truth is that great _depositum_ committed to the care of his church, which is therefore called the pillar of truth, 1 Tim. iii. 15; because as princes or rulers put their proclamations on pillars for the better information of their subjects, so doth his church hold out truth to the world. Holiness is maintained by truth, our ways are directed by it, and by it are we forewarned of Satan’s devices, John xvii. 17. Now the prince of darkness carrying himself in as full an opposition to the God of truth as he can in all his ways, God’s interest in truth will sufficiently discover the devil’s design to promote error; for such is his hatred of God, that, though he cannot destroy truth, no more than he can tear the sun out of the firmament, yet he will endeavour by corrupting the copy to disgrace the original. Though he cannot break Christ’s sceptre, yet by raising error he would hinder the increase of his subjects; though he cannot remove the rock upon which the church is built, he will endeavour to shake it, or to interrupt the building, and to tear down God’s proclamation from the pillar on which he hath set it to be read of all; and if we can conceive what a hatred the thief hath to the light, as it contradicts and hinders his designs, we may imagine there is nothing against which the devil will use greater contrivances than against the light of truth. He neither can nor will make a league with any, but upon the terms that Nahash propounded to the men of Jabesh-Gilead—that is, that he may ‘put out their right eye,’ and so ‘lay it for a reproach upon the Israel of God,’ 1 Sam. xi. 3. It is the work of the Holy Spirit ‘to
