A _third_ consideration, whereby the duty of renewing covenant with God appears to be difficult and weighty, was deduced from _the manner and way of engaging_; whereunto several things of great difficulty to be attained were showed to be absolutely necessary, as, 1st, _Judgment_, to know, and in some measure comprehend, the nature of the duties to be engaged to, and the advantages flowing from the right entering into, and keeping of the covenant, and the losses redounding to the breakers thereof. 2d, _Seriousness_, which, if ever it be in exercise, will certainly then be most lively, when the soul is entering upon a work of so high import, as making a covenant with God; for then the creature has one of two things to look for, either covenant blessings, or covenant curses, according as it performs or not performs the tenor of the covenant. 3d, _Deliberation_; rashness in covenanting is of dangerous consequence: 'tis not the example of others only, nor raw flashes of conviction or love, nor external considerations, as gain, honor, men's approbation, &c., that must induce to this duty; but a fixed permanent purpose of heart and soul, rationally and deliberately entered into. 4th, _Heart-integrity_, That it be done with all the heart, 2 Chron. xv. 15, for the man brings himself under a curse, that "having a male in his flock, sacrificeth to the Lord a corrupt thing." Mal. i. 14. A _fourth_ consideration, from whence the work of covenanting comes to be a difficult and hard work, was deduced from the _way and manner of performing_ the duties engaged to; which is (as 'tis expressed in the covenant) with sincerity, reality, and constancy; the difficulty of attaining to these qualifications in the performance of covenant-duties, arising partly from the strength of corruption within, the law of sin and death, which opposes the law of God; and partly from the strength of snares and temptations from without; which requires, that (as becomes covenanted children) there be a daily recourse to Jesus Christ, for light to discover, and strength to overcome these corruptions and temptations; and life, that the soul turn not dead and insensible under them. A _fifth_ consideration, from whence the difficulty of covenanting with God is sometimes heightened, was taken from _the meanness of such as attempt the work_. When the great ones, the nobles that are called _the shields of the earth_, do not afford their authority and patrociny, as an encouragement to the undertaking; and when the wise and learned will not employ their learning, parts, and abilities for the facilitating thereof; but the mean and weakest are left to do the work alone. This was no small difficulty and discouragement to the Tekoites, in their building and repairing the wall of Jerusalem, "That their nobles put not their necks to the work of their Lord." Neh. iii. 5.
