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!"
