GRACE DEEPLY INTERIOR.
While you perceive nothing sensible, or apparent, in your religious state, there is, at the same time, evidence to others of a hidden spring of life within your soul. God does not give you the sweet rain which, falling, clothes all the surface of the soul with verdure, but he gives you the deep well-spring, by which means you live and flourish, and produce, not herbs and flowers, which are born and die in the same day, but substantial fruits, ripening for eternity. David said, the life of man upon the earth is as grass, which groweth up in the morning, and withers in the evening. This refers to the natural life, but it is also true of the selfish life of man. It flourishes in the morning of the spiritual life, but no sooner does the sun of righteousness arise in his warmth, than this life withers and is cut down. The righteous are as a tree planted by the rivers of water, whose leaf is always green. This is because the roots are well watered by the deep-flowing current.
God never ceases to operate in your heart. The calm, resigned state of your soul is proof of this.
Take good care of your health. Do not labor beyond your strength. God will abundantly reward you for your labors of love in behalf of others. These are labors he never fails to recompense. I pray God, my dear F., to preserve you for his work. I have many things to say, but I forbear. Your time is precious.
