…If anyone would tell you the shortest, surest way to all happiness and all perfection, he must tell you to make it a rule to yourself to thank and praise God for everything that happens to you. For it is certain that whatever seeming calamity happens to you, if you thank and praise God for it, you turn it into a blessing. Could you therefore work miracles, you could not do more for yourself than by this thankful spirit, for it heals with a word speaking, and turns all that it touches into happiness.
…though it be the noblest sacrifice that the greatest Saint can offer unto God, yet is it not tied to any time, or place, or great occasion but is always in your power and may be the exercise of every day. For the common events of every day are sufficient to discover and exercise this temper and may plainly show you how far you are governed in all your actions by this thankful spirit.
