Proverbs 4:23,  Keep thy heart with all diligence; for out of it are the issues of life.

Keep means to guard, diligence means to guard a deposit.

This son is to think of that which has been deposited in his heart, his fathers words, as a treasure that needs guarding and watching lest it is stolen by another.

That other is the world, the flesh and the devil.

The world attacks the heart with other competing words.

It is constantly on the attack against the fatherís words and attempts to diminish those words and substitute those words with its own words.

The flesh cries out to the heart to open up the doors and give room for its passions.

The devil comes with subtleties, with deceits to try to break down the walls built by the fatherís words.

But this father knows the enemies of the heart and he knows that that is where all that is important, issues from.

All actions, all behaviors, all thoughts, all deeds all affections, all desires, all motives, all pursuits come from the heart.

The mouth, the eyes, the feet the hands, all are directed by the heart.

Keep thy heart with all diligence; for out of it are the issues of life.

In other words the father intends for the deposit of his word in his sonís heart to be maintained and not lost and to be used to defend against the world, the flesh and the devil.

For it is out of the good treasure of the heart that a man brings forth good things.

But good things cannot be brought out of a heart unless good things have been deposited.

The Bank account of the heart.

How much more important than a bank account for college.

And this father intends to have daily deposits in his sonís heart.

This father intends for these deposits to begin early in his sonís life so that the seed of the word will grow into a strong imbedded plant in the heart of the son.

This is possible when starting the process of implanting doctrine immediately upon the motherís completion of the weaning of his son.

This father is a believer of Isaiah 28:9,10 which gives direction to him to begin doctrine early in the life of his son,

Whom shall he teach knowledge? and whom shall he make to understand doctrine? them that are weaned from the milk, and drawn from the breasts. For precept must be upon precept, precept upon precept; line upon line, line upon line; here a little, and there a little:

The father fully believes this for this father works with eternity in view.

His purpose is not temporal but his purpose is eternal and his words are such as to promote that purpose.

And in that keeping of the heart there is to be an abhorrence of the froward mouth for the father tells his son in:  Go to Proverbs 4:24
