Greg Barrow, one of the leading Covenanter scholars of our day, calls this "one of the best books on covenanting."
The great Jehovah possesses in himself, and exercises all that authority, by which the children of men are bound to obedience, and has given them his law as the regulating standard of their actions; but, in order more effectually to promote the ends thereof among men, he has instituted in his word, vowing and swearing unto him, and covenanting with him, as his ordinances unto them, as their indispensable duty.
He has given to Christians a power over themselves, or a right of self-government, whereby they, in agreeableness to the prescriptions of his law, dispose of themselves, and voluntarily engage themselves unto his obedience.
The church's covenanting with God, and vowing and swearing unto him, are the principal ways by which they exercise this right, and use this power which God has given them, by disposing of themselves as the law requires, in taking upon themselves the yoke of Christ which is easy, and his burden which is light.
When Christians are convinced, by the light of God's word, that these exercises are their duty, and, in consequence thereof, do actually promise, vow and swear unto the Lord, or covenant with him, that they shall, in the strength of his grace, abstain from evil, and practice holiness; they are under obligation to obedience, by their own religious and voluntary promises, vows, oaths and covenants, as well as they are bound thereunto, by the infinite authority of God in his law.
