Your chief study

(Richard Baxter)

"Above all else, guard your heart, for it
 is the wellspring of life!" Proverbs 4:23

See that your chief study is about your heart:
  that there, God's image is planted;
  that there, His interests are advanced;
  that there, the world and flesh are subdued;
  that there, the love of every sin is cast out;
  that there, the love of holiness grows.

"I, the Lord, search the heart and examine
 the mind!" Jeremiah 17:10
