To illustrate the nature and present the claims of an observance so carefully kept by many of the best of our race as religious Covenanting, is an attempt so inviting as to seem not unworthy of the application of the greatest diligence and care, and the most varied and extensive resources of the human mind. What the word of God unfolds concerning it, is addressed to the most resolute consideration of all, and is capable of engaging the most extensive and prolonged investigation. And yet, though none have found this subject, like all God's judgments, else than a great deep, still in meditating upon it, the ignorant have been brought to true knowledge, and the wise have increased in wisdom. "The secret of the Lord is with them that fear him; and he will shew them his covenant."[1] Impressions of its importance have universally continued to appear on the heart of man; but with that varied indistinctness which may, and ought to be remedied, those have been marked. In the Scriptures alone, its precise character is drawn. Mutual federal engagements, concerning things religious and civil, whether entered into merely by simple promise, or confirmed by solemn oath, have been made from the highest antiquity to the present. The hostility to some such engagements, and also the proud disregard for their obligations, which have been evinced by some in all ages, demand a most careful examination into their nature and design. And the delightful approval of conscience awarded to right-heartedness in making and fulfilling such of these as were warranted, gives a reason for the careful study of their character, the most pleasing and satisfactory. Furnished with the key of Scripture, approaching the subject, we are enabled to open the mysteries in which ignorance and prejudice had shut it up; and equipped with the armour of light shooting forth its heavenly radiance, in safety to ourselves we assail the darkness thrown around it, and behold the instant flight of the spirits of error which that darkness contains. Standing alone in beauteous attractions descended from heaven upon it, this service beckons us to approach it, and engages to connect extensive good with a proper attention to its claims. The observance, under various phases, is described in Scripture as an undisputed and indisputable reality. There, its nature and the manner of performing it are defined; its character as a duty, the compass of its matter, and the obligation entailed by engaging in it are exhibited; the provision made for the continuance of it, its adaptations, sovereign appointment, sanction, and character as a privilege, and powerful motives to engage in it afforded in its signs, are presented; and its history, anterior and prospective, its recommendations found in the practice of the church in gospel times, its advantages, and claims, are distinctly revealed.
