The qualities good and evil can only exist in the mind as they are measured by a supreme law. “If we deny the existence of a Divine law obligatory on men, we must deny that the world is under Divine government, for a government without rule or law is a solecism.” _Watson’s Theo. Inst._ vol. i. p. 8. Divine laws must be the subject of revelation. The law of a visible power cannot be known without some indications, much less the will of an invisible power, and that, too, of an order of existence so far above our own that even its mode is beyond our comprehension. Very true, the providence of God towards any particular course of conduct may be taken as the revelation of his will thus far, but, by no means, preclude the necessity of a more direct revelation, until man shall be able to boast that he comprehends the entire works of Jehovah. The difference between the Christian and the mere theist is, while the latter admits that a revelation of the will of God is or has been made by significant actions, he contends _that_ is a _sufficient revelation_ of the laws of God for the guidance of man. “They who never heard of any external revelation, yet if they knew from the nature of things what is fit for them to do, they know all that God can or will require of them.” _Christianity as Old as Creation_, p. 233. “By employing our reason to collect the will of God from the fund of our nature, physical and moral, we may acquire not only a particular knowledge of those laws, which are deducible from them, but a general knowledge of the manner in which God is pleased to exercise his supreme powers in this system.” _Bolingbroke’s Works_, vol. v. p. 100. “But they who believe the holy Scriptures contain a revelation of God’s will, do not deny that indications of his will have been made by _actions_; but they contend that they are in themselves imperfect and insufficient, and that they were not designed to supersede a direct revelation. They also hold, that a direct communication of the Divine will was made to the progenitors of the human race, which received additions at subsequent periods, and that the whole was at length embraced in the book called, by way of eminence, the Bible.” _Watson’s Theo. Inst._ vol. i. p. 10. Faith “is the substance of things hoped for, the evidence of things not seen.” _Heb._ xi. 1. As an instance of revelation, we present _Lev._ xxv. 1, and 44, 45, 46. “And the Lord spake unto Moses in Mount Sinai, saying: Both thy bondmen and bondmaids, which thou shalt have, shall be of the heathen that are round about you; of them shall ye buy bondmen and bondmaids.” “Moreover, of the children of the strangers that do sojourn among you, of them shall ye buy, and of their families that are with you, which they begat in your land: and they shall be your possession.”
