Chapter 15 in Book Three of The Imitation of Christ, prompts Fr. Robert Nixon to advise we preface all our prayers with the words from The Lord’s Prayer, “Thy will be done.”
“Everything we ask for from God,” Fr. Nixon comments, “We should say, ‘God, if this is in accordance with Your will and Your will is my salvation and my ultimate good, so if it’s what You want, let it be done.’ There’s a certain amount of humility in this in giving up our own preferences, realizing that sometimes we can be mistaken about what’s good for us and what’s actually bad for us. A lot of the time, the things which our hearts seem to want might actually be for our own final destruction, and, of course, we have no way of knowing it at the time.”
