Keep Your Heart - Part 6

Keep your heart as you would keep a watch. The heart will unwind to the earth; therefore wind it up every morning and evening by prayer. The motion of a watch is not constant: sometimes it goes fast, sometimes slower. And so it is with the heart: sometimes it goes faster in vanity and sometimes it goes slower in duty. Therefore set this spiritual watch by the sundial of the Word. ~Thomas Watson, The Spiritual Watch
