Mark the Ascetic - On the Spiritual Law 158-161

158. All good things come from God providentially, and those who bring them are the servants of what is good.
159. Accept with equanimity the intermingling of good and evil, and then God will resolve all inequity.
160. It is the uneven quality of our thoughts that produces changes in our condition. For God assigns to our voluntary thoughts consequences which are appropriate but not necessarily of our choice.
161. The sensible derives from the intelligible, by God's decree providing what is needed.
