None may be excused for not engaging in Covenanting. Those who perform the duty in secret, are called to discharge it on some occasions in public. To vow in secret, is but partially to do duty. Secret prayer is not a sufficient substitute for that which is public. The doing of duty to our neighbour and to ourselves, cannot be reckoned as the fulfilment of our obligations to God. And vowing to Him in an individual capacity, will not be accepted for vowing and swearing to Him in a public associate character. Again, those who vow neither in secret nor in public, are called to do both. Is it urged, that it is a dreadful thing by the vow or oath to come under obligations that might not be fulfilled? It is answered, Is it a fearful thing to do what God commands? What ought to be vowed ought to be fulfilled, whether vowed or not; and if duty be vowed falsely, or not vowed at all, sin is committed. Is it not a dreadful thing, by refusing to do this duty, to rebel against Him who said, "Vow and pay unto the Lord your God?" He is guilty and degraded who breaks an oath; but low indeed is the moral state of him who, lest he should not perform his obligation, refuses to swear. And how wretched is the condition of those who will neither vow nor swear, lest they might, as they certainly would, be thereby bound to duty! The swearing of an oath is a solemn act. To disregard it, whether by refusing to take it when called to it, or by not performing it when lawfully taken, is highly criminal and dangerous. The doom of the impenitent and Covenant breaker is awful; but those who do not, in one way or other, truly vow to God, have no hope. Refraining from vowing to him, man sustains a character no higher than the wicked who restrain prayer before God. It is not the right of any one, according to his pleasure, to abstain from entering into Covenant with God. It is a duty to obey God's law; Covenanting is one of the duties of that law; it is therefore a duty to engage in its performance. No man has a right to refuse to do so. It is our duty to serve God. It is our duty to promise to serve him. In certain cases, it is our duty to vow and swear to serve him. What it is our duty to do, it is our duty to engage by Covenant with Him to do. If men neither serve God nor vow to serve him, they are chargeable with two classes of sins;--that of disregarding the duty of Covenanting with God,--and that of refusing to perform duties, one of which is the performance of that exercise. If men vow to serve God, but do it not, they greatly sin; being chargeable with an omission of duty, in one case at least, they have rebelled. If they do not vow to serve God, whatever may be the nature of their obedience, that, by being deficient as to Covenanting, is imperfect. To hope to be more safe from condemnation by not vowing than by vowing, is to cherish a love to sin, and to betray the workings of a heart which regards not how God may be
