The great business of a Christian's life!
 
(John Flavel)

"Guard your heart above all else - for it determines the course of your life!" Proverbs 4:23

The heart is the seat of principles - and the fountain of actions. The eye of God is, and the eye of the Christian ought to be - principally fixed upon it.

The greatest difficulty in conversion - is to win the heart to God.
The greatest difficulty after conversion - is to keep the heart with God.

Here lies the very pinch and stress of religion; here is that that makes the way to life a narrow way, and the gate of Heaven a straight gate.

The keeping and right managing of the heart in every condition - is the great business of a Christian's life!

"Oh, for a holier heart!
 Oh for a heart to hate sin more!
 Oh for a heart to love God more - and to walk more closely with Him!
 Lord, whatever you deny me - do not deny me such a heart!
 Give me a heart to fear You, love You and delight in You!"
