When the love of God obtains the mastery of a soul, it produces in it an insatiable desire to labor for the Beloved; so that, though it may perform many and great works and spend much time in His service, all seems nothing, and it constantly grieves at doing so little for its God, and if it could annihilate itself and perish for Him, it would be well pleased. And so it considers itself unprofitable in all that it does and regards its life as idle; for, as love teaches it what God merits, by this clear light it sees all the defects and imperfections of its actions, and thus derives confusion and grief from them all. And as it feels that its work is very poor to be offered to so great a Lord, it is at the greatest distance from vainglory and presumption, and from condemning others.----St. John Chrysostom
