Bl. John Henry Newman, Doctor of Conscience and Doctor of Tradition, remains one of my dear friends in Heaven. Some of his prayers and devotions are as puissant today as they were when they were first composed. I am consoled by and draw courage from this extended passage of the Meditations and Devotions:

I have always thought this portrait captures the humanity and essential kindness of Cardinal Newman. (Source)
GOD has created all things for good; all things for their greatest good; everything for its own good. What is the good of one is not the good of another; what makes one man happy would make another unhappy. God has determined, unless I interfere with His plan, that I should reach that which will be my greatest happiness. He looks on me individually, He calls me by my name, He knows what I can do, what I can best be, what is my greatest happiness, and He means to give it me.
God knows what is my greatest happiness, but I do not. There is no rule about what is happy and good; what suits one would not suit another. And the ways by which perfection is reached vary very much; the medicines necessary for our souls are very different from each other. Thus God leads us by strange ways; we know He wills our happiness, but we neither know what our happiness is, nor the way. We are blind; left to ourselves we should take the wrong way; we must leave it to Him.
Let us put ourselves into His hands, and not be startled though He leads us by a strange way, a mirabilis via, as the Church speaks. Let us be sure He will lead us right, that He will bring us to that which is, not indeed what we think best, nor what is best for another, but what is best for us.
O, my God, I will put myself without reserve into Thy hands. Wealth or woe, joy or sorrow, friends or bereavement, honour or humiliation, good report or ill report, comfort or discomfort, Thy presence or the hiding of Thy countenance, all is good if it comes from Thee. Thou art wisdom and Thou art love—what can I desire more? Thou hast led me in Thy counsel, and with glory hast Thou received me. What have I in heaven, and apart from Thee what want I upon earth? My flesh and my heart faileth: but God is the God of my heart, and my portion for ever.

God has created me to do Him some definite service; He has committed some work to me which He has not committed to another. I have my mission—I never may know it in this life, but I shall be told it in the next. Somehow I am necessary for His purposes, as necessary in my place as an Archangel in his—if, indeed, I fail, He can raise another, as He could make the stones children of Abraham. Yet I have a part in this great work; I am a link in a chain, a bond of connexion between persons. He has not created me for naught. I shall do good, I shall do His work; I shall be an angel of peace, a preacher of truth in my own place, while not intending it, if I do but keep His commandments and serve Him in my calling.
Therefore I will trust Him. Whatever, wherever I am, I can never be thrown away. If I am in sickness, my sickness may serve Him; in perplexity, my perplexity may serve Him; if I am in sorrow, my sorrow may serve Him. My sickness, or perplexity, or sorrow may be necessary causes of some great end, which is quite beyond us. He does nothing in vain; He may prolong my life, He may shorten it; He knows what He is about. He may take away my friends, He may throw me among strangers, He may make me feel desolate, make my spirits sink, hide the future from me—still He knows what He is about.
O Adonai, O Ruler of Israel, Thou that guidest Joseph like a flock, O Emmanuel, O Sapientia, I give myself to Thee. I trust Thee wholly. Thou art wiser than I—more loving to me than I myself. Deign to fulfil Thy high purposes in me whatever they be—work in and through me. I am born to serve Thee, to be Thine, to be Thy instrument. Let me be Thy blind instrument. I ask not to see—I ask not to know—I ask simply to be used.
