9. We should lie open to the influences and rays of light, by exercising faith in earnest desires; as also patient waiting for and single looking to him, minding his name and his relations, promises, and engagements, and the strengthening of our faith and confidence. 10. We should labour to keep fast whatever he teacheth us by his word and Spirit, and not prove leaking vessels. This the apostle exhorteth to, Heb. ii. 1, "Therefore we ought to give the more earnest heed to the things which we have heard, lest at any time we should let them slip;" yea, and we should be established "in the truth," 2 Pet. i. 12. 11. We should beware of resting on a form of the truth, as those did, of whom we read, Rom. ii. 20; and of holding the truth in unrighteousness, as those, Rom. i. 18; and of disobeying it, as those mentioned in Rom. ii. 8. See also Gal. iii. 1; v. 7. 12. But on the contrary, we should so receive truth, as that it might rule and be master in us, captivate judgment, will, and affections, and break out into the practice. And this recommendeth several duties, such as, (1.) To have the truth in us; while as, if we practise otherwise, "the truth is not in us," 1 John i. 8; ii. 4. (2.) To be of the truth, as belonging to its jurisdiction, power, and command, 1 John iii. 19. John xviii. 37. (3.) To do the truth, by having true fellowship with him, 1 John i. 6; and "to walk in the truth," 2 John iv. 3. John iv. Psalm lxxxvi. 11. (4.) To have the loins girt with truth, Eph. i. 14. (5.) To receive the love of the truth, 2 Thess. ii. 10. (6.) To be instructed of him, "as the truth is in Jesus," Eph. iv. 21. (7.) To purify the soul in obeying the truth, 1 Pet. ii. 22. This shall suffice for clearing up, and applying in the general this excellent truth, that Christ is the truth. We shall now come and make some more particular use of this precious point, by speaking to some particular cases (which we shall instance in, by which the understanding Christian may be helped to understand how to carry and how to make use of Christ in other the like cases), wherein Christ is to be made use of as the truth, and show how believers are to make use of him in these cases as the truth.
