Now and then, set aside for yourself a day on which, without hindrance, you can be at leisure to praise God and to make amends for all the praise and thanksgiving you have neglected all the days of your life to render to God for all the good he has done. This will be a day of praising and thanksgiving and a day of jubilation, and you will celebrate the memory of that radiant praise with which you will be jubilant to the Lord for eternity, when you will be satisfied fully by the presence of God, and the glory of the Lord will fill your soul.
