In a moment shall they die - Both are equally dependent on the Almighty for their breath and being; the mighty as well as the poor. If the great men of the earth have abused their power, he sometimes cuts them off by the most sudden and unexpected death; and even at midnight, when in security, and least capable of defense, they are cut off by the people whom they have oppressed, or by the invisible hand of the angel of death. This appears to be spoken in reference to Eastern tyrants, who seldom die a natural death.

Covenanting Confers Obligation.
As it has been shown that all duty, and that alone, ought to be vowed to God in covenant, it is manifest that what is lawfully engaged to in swearing by the name of God is enjoined in the moral law, and, because of the authority of that law, ought to be performed as a duty. But it is now to be proved that what is promised to God by vow or oath, ought to be performed also because of the act of Covenanting. The performance of that exercise is commanded, and the same law which enjoins that the duties …

Whether a Sin is Aggravated by Reason of the Condition of the Person against whom it is Committed?
Objection 1: It would seem that sin is not aggravated by reason of the condition of the person against whom it is committed. For if this were the case a sin would be aggravated chiefly by being committed against a just and holy man. But this does not aggravate a sin: because a virtuous man who bears a wrong with equanimity is less harmed by the wrong done him, than others, who, through being scandalized, are also hurt inwardly. Therefore the condition of the person against whom a sin is committed …

Whether Predestination is Certain?
Objection 1: It seems that predestination is not certain. Because on the words "Hold fast that which thou hast, that no one take thy crown," (Rev 3:11), Augustine says (De Corr. et Grat. 15): "Another will not receive, unless this one were to lose it." Hence the crown which is the effect of predestination can be both acquired and lost. Therefore predestination cannot be certain. Objection 2: Further, granted what is possible, nothing impossible follows. But it is possible that one predestined---e.g. …
