Acts 15:18 - Coke's Commentary on the Holy Bible

Known unto God are all his works— The apostle plainly speaks here, not of God's works in the natural world, but of his dispensations towards the children of men: now he could not know those, without knowing the actions and characters of particular persons, on a correspondence to which, the wisdom and goodness of those dispensations is founded. Thus, for instance, he must have knownthat there would be Gentile idolaters, (a thing as dependant on the freedom of the human mind, as any thing that we can imagine,) or he could not have known that he would call them into his church. This text, therefore, must remain an unanswerable proof, amongst a thousand more from the word of God, that he certainly foreknows future contingencies. Dr. Clarke's paraphrase of the text is, "The method of his universal government, through the whole system, both of the natural and moral world, is according to certain uniform rules eternally established by unerring wisdom."
