Now there are two forms of desertion: for there is desertion in the matters of guidance and training, and there is complete and hopeless desertion.
The former has in view the restoration and safety and glory of the sufferer, or the rousing of feelings of emulation and imitation in others, or the glory of God: but the latter is when man, after God has done all that was possible to save him, remains of his own set purpose blind and uncured, or rather incurable, and then he is handed over to utter destruction, as was Judas. (Matthew 26:24)
May God be gracious to us, and deliver us from such desertion.
St John of Damascus
