Chapter 32 of The Way of Perfection is a profound treatise on suffering, focusing on the idea that, when we pray “Thy will be done,” we are, like Jesus and Mary, assenting to God’s will, not just in the good stuff but in the bad stuff, and the suffering we will endure.
Let me put it in another way. Consider, daughters, that, whether we wish it or no, God’s will must be done, and must be done both in Heaven and on earth. Believe me, then, do as I suggest and make a virtue of necessity.
O my Lord, what a great comfort it is to me that Thou didst not entrust the fulfillment of Thy will to one so wretched as I! Blessed be Thou for ever and let all things praise Thee. May Thy name be for ever glorified. I should indeed have had to be good, Lord, if the fulfillment or non-fulfillment of Thy will [in Heaven and on earth] were in my hands. But as it is, though my will is not yet free from self-interest, I give it to Thee freely. For I have proved, by long experience, how much I gain by leaving it freely in Thy hands. O friends, what a great gain is this — and how much we lose through not fulfilling our promises to the Lord in the Paternoster, and giving Him what we offer Him!
Before I tell you in what this gain consists, I will explain to you how much you are offering, lest later you should exclaim that you had been deceived and had not understood what you were saying. Do not behave like some religious among us, who do nothing but promise, and then excuse ourselves for not fulfilling our promises by saying that we had not understood what we were promising. . . .
So I want you to realize with Whom (as they say) you are dealing and what the good Jesus offers on your behalf to the Father, and what you are giving Him when you pray that His will may be done in you: it is nothing else than this that you are praying for. Do not fear that He will give you riches or pleasures or great honors or any such earthly things; His love for you is not so poor as that. And He sets a very high value on what you give Him and desires to recompense you for it since He gives you His Kingdom while you are still alive. Would you like to see how He treats those who make this prayer from their hearts? Ask His glorious Son, Who made it thus in the Garden. Think with what resolution and fullness of desire He prayed; and consider if the will of God was not perfectly fulfilled in Him through the trials, sufferings, insults and persecutions which He gave Him, until at last His life ended with death on a Cross.
So you see, daughters, what God gave to His best Beloved, and from that you can understand what His will is. These, then, are His gifts in this world. He gives them in proportion to the love which He bears us. He gives more to those whom He loves most, and less to those He loves least; and He gives in accordance with the courage which He sees that each of us has and the love we bear to His Majesty. When He sees a soul who loves Him greatly, He knows that soul can suffer much for Him, whereas one who loves Him little will suffer little. For my own part, I believe that love is the measure of our ability to bear crosses, whether great or small. So if you have this love, sisters, try not to let the prayers you make to so great a Lord be words of mere politeness but brace yourselves to suffer what His Majesty desires. For if you give Him your will in any other way, you are just showing Him a jewel, making as if to give it to Him and begging Him to take it, and then, when He puts out His hand to do so, taking it back and holding on to it tightly.
