Abba Anthony said, “It is not seemly for us to remember the time which has passed, but let a man be each day as one who begins his toil, so that the excessive weariness (which we shall feel) may be to our advantage. And let him say, as Paul said, “That which is behind me I forget, and I reach out to that which is before me’ (Philippians 3:13). And let him also remember the word of Elijah who said, ‘As the Lord lives, before Whom I stand this day'” (1 Kings 17:1).
