Augustine of Hippo — as excerpted in the Catena Aurea on John 6:35-40

“(Tr. xxv. 14) That inner place, whence there is no casting out, is a great sanctuary, a secret chamber, where is neither weariness, or the bitterness of evil thoughts, or the cross of pain and temptation: of which it is said, Enter thou into the joy of thy Lord. (Mat. 25)”
