The story of St. Isaac, a great ascetic who was tricked by the devil who appeared to him in bright light, saying he was Christ. St. Isaac, after prostrating before him, was overcome by demonic power. They made him dance all night, leaving him near dead by the morning. After an arduous struggle, and with immense help from St. Anthony and St. Theodosius, St. Isaac regained his strength and abilities to take care of himself. He no longer lived as a hermit, but stayed with the brethren where he redoubled his ascetic efforts. By the grace of God, he conquered the demons and received a eternal crown from Christ.
