2. Nor would the believer think, that hereby he shall be kept altogether free of fainting. The heart, now and then, through fear and misbelief, may fall into a fit of fainting, and think all is gone; and yet he may carry poor souls through, and make his strength perfect in their wickedness, 2 Cor. xii. 9; that when they are supported and carried through the temptation, they may sing praise to him, and not ascribe any thing to themselves--remembering how often they were fainting, and almost giving over the cause as desperate and hopeless. 3. They would not think it strange, if, in the time of their wrestling with difficulties, the Lord hide his face from them, and give not them that joyful access unto him in prayer, that sometimes they have met with; for the Lord may see it fit to put them to this point of trial among the rest, to see if the love of his glory and truth will keep them standing, when they want the encouragement that might be expected in that way; and if pure conscience to the command and authority of God, will keep from siding with an evil way, when the soul is destitute of all sensible encouragement, both from within and from without. 4. In all this business believers should carry singly with an eye to God's glory; and should not be acted with self-ends, or drawn by carnal and selfish motives. They should not desire stability and through-bearing to be seen of men, or to gain applause and praise of men; lest God be provoked to leave them to themselves, and they at length come off with discredit, as did Peter. Therefore they should strive against these carnal motions of the heart, and labour for spirituality, singleness of heart, and truth in the inward parts, which the Lord desireth, Psalm li. 6. CHAPTER XVI. HOW TO MAKE USE OF CHRIST AS THE TRUTH, WHEN ERROR PREVAILETH, AND THE SPIRIT OF ERROR CARRIETH MANY AWAY. There is a time when the spirit of error is going abroad, and truth is questioned, and many are led away with delusions. For Satan can change himself into an angel of light, and make many great and fairlike pretensions to holiness, and under that pretext usher in untruths, and gain the consent of many unto them; so that in such a time of temptation many are stolen off their feet, and made to depart from the right ways of God, and to embrace error and delusions instead of truth. Now the question is, how a poor believer shall make use of Christ, who is the truth, for keeping him steadfast in the truth, in such a day of trial, and from embracing of error, how plausible soever it may appear. For satisfaction to this we shall propose these few things:
