Pride

It is shameful to be proud of the adornments that are not your own, but utter madness to fancy one deserves God’s gifts. Be exalted only by such achievements as you had before your birth. But what you received after your birth, as also birth itself, God gave you. Only those virtues which you have obtained without the co-operation of the mind belong to you, because your mind was given you by God. Only such victories as you have won without the co-operation of the body have been accomplished by your efforts, because the body is not yours, but a work of God. -The Ladder of Divine Ascent, step 23.16, St. John Climacus
