“Keep thy heart with all diligence.” — Pro_4:23. “The peace of God shall keep your hearts.” — Php_4:7.
IN MOST of the old castles there is an inner keep, which is protected, not only by mighty walls and bastions, but by the portcullis at the gate, and sentries at every approach, who challenged every one that passed in and out. So the heart is continually approached by good and evil, by the frivolities and vanities of the world and the insidious suggestions of the flesh. It is like an inn or hostelry, with constant arrivals and departures. Passengers throng in and out, some of them with evil intent, hoping to find conspirators, or to light fires that will spread until the whole being is swept with passion, consuming in an hour the fabric of years to ashes.
We need, therefore, to be constantly on the watch; we must keep our heart above all else that we guard, for out of it are the issues of life (R.V. marg.). Our Lord says that “out of the heart of man come forth evil thoughts, murders, adulteries, thefts,” etc. The devil and the world without would be less to be feared, if there were not such strong tendencies to evil within—many of them inherited from long lines of ancestors, who, alas! pass down to us the worst features of their characters equally with the best.
Keep it Clean. Just as the eye of the body is perpetually washed with tear-water, so let us ask that the precious blood of Christ may cleanse away any speck of impurity. Remember how delicate a thing the heart is, and how susceptible to the dust of an evil thought, which would instantly prevent it becoming the organ of spiritual vision. Sursum Corda! Lift up your hearts! We lift them up unto the Lord!
The Sentinel of Peace. Then the Peace of God will become the warden or sentry of the heart, and it passeth understanding! We can understand the apparent peace of some men. They have made money, and their gold-bags are piled around them as a fortress; they have rich and influential friends, within whose protection they imagine they will be sheltered and defended; they enjoy good health, and are held in high esteem. We can understand such peace, though it often proves ephemeral! But there is a peace that passeth understanding! It is to this that our Lord refers when He says, “My Peace I give unto you; not as the world giveth.” “Let not your heart be troubled, neither let it be afraid.”
Keep me, Heavenly Father, as the apple of Thine eye; defend me by Thine Almighty power; hide me from this strife of tongues and the fiery darts of the wicked one. May my heart be as the palace which the Stronger than the strong man keeps in perfect peace. AMEN.
