Outside of the authors of the Bible, Dostoevsky was the most prophetic author I’ve ever read. I sometimes wonder if he had the spiritual gift of prophecy.
Perhaps, but then again, if not in fellowship with God at the time of spiritual influence, one must discern if he was under demonic influence or guidance by God the Holy Spirit.
A good work of God is the faith of the believer. His work always glorifies the Son. If Dostoevsky’s work glorifies the Son, then perhaps he was under the guidance of God. On the other hand, if not glorifying of the Son, then the work is discernible from that of God.
