In the new year that comes, do all for the glory of God... Saint John Chrysostom

“Whether you eat, whether you drink, whether you do some other thing, do all for the glory of God” [1 Cor. 10:31]. If we pray, if we fast, if we accuse, if we pardon, if we praise, if we censure, if we enter, if we exit, if we sell, if we buy, if we are silent, if we converse, if we do any thing else whatsoever, let us do all for the glory of God, and if something be not for the glory of God, neither let it be done, nor be spoken by us; but in place of a great staff, in place of arms and safeguard, in place of unspeakable treasures, wherever we might be, let us carry around this word with us, having inscribed it upon our understanding, so that doing and speaking and trafficking all things for the glory of God, we shall obtain the glory that is from him both in this world and after the journey here [i.e. after this life]. “For those that glorified me”, he says, “I will glorify” [1 Sam 2:30; (1 Reg. 2.30 LXX)]. Not therefore with words, but also through deeds let us glorify him continually with Christ our God, because all glory befits him, honor and worship, now and always unto the ages of ages. Amen."
