In short, knowing that whatever may happen is ordained by the Lord, he will receive it with a peaceful and thankful heart, that he may not be guilty … - John Calvin

We must resist wandering thoughts in prayer. Raising our hands reminds us that we need to raise up our minds to God, setting aside all irrelevant thoughts.

Just as a maistre Fifi mocks those who hold their noses [in his presence]. because he has handled filth for so long that he can no longer smell his own foulness; so likewise do idolaters make light of those who are offended by a stench they cannot themselves recognize. Hardened by habit, they sit in their own excrement, and yet believe they are surrounded by roses.

If he has deserved no kindness, but just the opposite, because he has maddened you with his injuries and insults, even this is no reason why you should not surround him with your affection and show him all sorts of favors.
