St. John Chrysostom on thanksgiving

Wouldest thou learn words of thanksgiving? Hearken unto the Three Children, saying, ‘We have sinned, we have transgressed. Thou art righteous, O Lord, in all that thou hast done unto us, because thou hast brought all things upon us by a true judgment’ (Prayer of Azariah; Book of Daniel LXX). For to confess one’s own sins, this is to give thanks with confessions unto God: a kind of thing which implies one to be guilty of numberless offenses, yet not to have the due penalty exacted. This man most of all is the giver of thanks.
