Seventh Letter: I pity you much. It will be a great relief if you can leave the care of your affairs to M_ and spend the remainder of your life only in worshipping God. He requires no great matters of us; a little remembrance of Him from time to time, a little adoration. Sometimes to pray for His grace, sometimes to offer Him your sufferings, and sometimes to return Him thanks for the favors He has given you, and still gives you in the midst of your troubles. Console yourself with Him the oftenest you can. Lift up your heart to Him at your meals and when you are in company. The least little remembrance will always be pleasing to Him.
