Do not pray for your heart’s desires, for they may not entirely harmonize with God’s purposes. Pray instead as you have been taught: ‘May your will be done in me.’ [Luke 22:42]. Pray to God this way about everything, that his will might be accomplished in you, for he only desires what is good and useful for your life, whereas you do not always request this.
–Evagrius Ponticus (345-399)
