14. He must be willing to receive and obey the truth at the dearest rate, especially of laborious study, and a self-denying life; not taking all to be truth that costeth men dear, nor yet thinking that truth indeed can be over-prized.[15] 15. He must be humble and self-suspicious, and come to Christ's school as a little child; and not have a proud overvaluing of himself and his own understanding. The proud and selfish are blind and cross, and have usually some opinions or interests of their own, that lie cross to duty, and to other men's good.[16] 16. He must have an eye to posterity, and not only to the present time or age; and to other nations, and not only to the country where he liveth. Many things seem necessary for some present strait or work that we would do (which in the next age may be of mischievous effects); especially in ecclesiastical and political professions, covenants and impositions, we must look further than our present needs. And many things seem necessary for a local, narrow interest, which those at a distance will otherwise esteem.[17] 17. He that will walk uprightly must be able to bear the displeasure of all the world, when the interest of truth requireth it; yea, to be rejected of learned and good men themselves; and account man's favour no better than it is; not to despise it as it is a means to any good, but to be quite above it as to his own interest. Not that uprightness doth use to make a man despised by the upright; but that it may bring him under their censure in some particulars, which are not commonly received or understood to be of God.[18] 18. He must make it a great part of the work of his life to kill all those carnal desires, which the sensual make it their work and felicity to please; that appetite, sense and lust, and self-will may not be the constant perverters of his life; as a fool in a dropsy studieth to please his thirst, and a wise man to cure it.[19] 19. He must live a life of constant and skilful watchfulness, apprehending himself in continual danger; and knowing his particular corruptions, temptations, and remedies. He must have a tender conscience, and keep as far as possible from temptation, and take heed of unnecessary approaches or delightful thoughts of sin. Oh what strong resolutions, what sound knowledge, have the near-baits of sensuality (meat, drink, lust, and pleasures) overcome! Never think yourselves safe among near-temptations, and opportunities of sinning.[20]
