The Lord is also in the habit of sending the most grievous infirmities. This is a much greater trial, especially if the pains are severe; in some ways, when they are very acute, I think they are the greatest earthly trial that exists—the greatest of exterior trials, I mean—however many a soul may suffer: I repeat that it is only to very acute pains that I am referring. For they affect the soul both outwardly and inwardly, till it becomes so much oppressed as not to know what to do with itself, and would much rather suffer any martyrdom than these pains. Still, at the very worst, they do not last so long—no longer, as a rule, than other bad illnesses do. For, after all, God gives us no more than we can bear, and He gives patience first.
-St. Teresa of Avila
Prayer for Perseverance
O Sacred Heart of Jesus, living and life-giving fountain of eternal life, infinite treasure of the Divinity, and glowing furnace of love, You are my refuge and my sanctuary. O adorable and glorious Savior, consume my heart with the burning fire that ever inflames Your Heart. Pour down on my soul the graces that flow from Your love. Let my heart be so united with Yours that our wills may be one, and mine may in all things be conformed to Yours. May Your Will be the rule both of my desires and of my actions.
