The fact that evil is permitted, a state enjoyed by everyone's internal man, makes it obvious that man has free will in spiritual matters.

The assertion that man has free will in spiritual matters must first be supported by general considerations, and after-wards by particular ones, such as anyone will acknowledge on first hearing. The general considerations are these. (1) Adam, the wisest of men, and his wife allowed themselves to be seduced by the serpent. (2) Their first son, Cain, killed his brother Abel, and Jehovah God did not deter them by talking to them, but only by cursing Cain after the event. (3) The Israelite nation in the desert worshipped the golden calf, although Jehovah saw this from Mount Sinai, and did not prevent it. (4) David counted the people and on account of this a plague was sent on them, of which so many thousands died; and it was not before but after this happened that God sent the prophet Gad to him and pronounced his punishment. (5) Solomon was permitted to set up idolatrous cults. (6) Many kings after him were permitted to profane the Temple and the holy things of the church; and finally that nation was permitted to crucify the Lord, (7) Mohammed was permitted to establish a religion which in many respects did not agree with Holy Scripture. (8) The Christian religion was divided into numerous sects, and each of these into heretical movements. (9) In Christendom there are so many ungodly people, and so much boasting about ungodly acts, as well as trickery and deceit, even practised on godly, just and honest people. (10) Injustice sometimes triumphs over justice in lawsuits and business dealings. (11) Even the ungodly are advanced to honours and become leaders in civil and religious life. (12) Wars are permitted, and then so many thousands are killed, and so many cities, nations and families have their goods looted, and suffer much besides. How can anyone explain such things except as the result of the free will enjoyed by every individual? In my book DIVINE PROVIDENCE (printed in Amsterdam in 1764, 234-274) it may be seen that the laws of permission too are laws of Divine providence; there too the facts mentioned above were explained.
