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

What does the word – keep, mean? It means hang onto, not let go, preserve. We are going to have to put forth the effort to keep our heart with all diligence.

What is diligence? Diligence is persevering, hard working, being careful in your work. It is the opposite of slothful and lazy. Diligence is done with careful, steady effort. It’s painstaking. If you’re going to keep your heart with all diligence, it’s going to take effort on your part.

I was recently reading a list of the 10 most secure places in the world. The most secure place on the list, in the United States, is Fort Knox. Why would Fort Knox be secure? It is secure because of all of the gold in Fort Knox. The walls are hundreds of feet thick. There are thousands of pounds of concrete poured into it. The walls are 52 feet tall. On every corner of the walls, there are lookout stations with guards and guns. Right by the door there is a box on each side that has a guard. In order to go in, one person can’t just dial the code and go in. It takes several people, with secret codes, to be able to go in

There is a place that should be more secure. That is our heart. Our heart needs to be more guarded than Fort Knox. There are ways that we can guard our heart. There are ways that the enemy is out to try to get little seeds to start growing so that our heart will not be like God wants it to be. We then wouldn’t keep our heart the way that God wants us to have it.

The enemy has things that he wants to get into our heart. That’s the reason why we have to actively guard our heart. The devil wants our heart so that he can pollute it and it can be destroyed. We need to love God with all our heart. There shouldn’t be any little rooms in our heart that we reserve for our self. It needs to all be given over to God.

Search me, O God, and know my heart: try me, and know my thoughts: And see if there be any wicked way in me, and lead me in the way everlasting. Psalms 139:23-24

The reason that we need to pray this way is because we don’t know our heart. A lot of people will say that their heart tells them something. They may feel something is right because their heart says it. It will not be right if it is contrary to the bible. Just because your heart says it, doesn’t make it right.

He that trusteth in his own heart is a fool: but whoso walketh wisely, he shall be delivered. Proverbs 28:26

That is the reason why we’ve got to have God change our heart and give us a new heart. If we want to keep our old heart in some way, we’re going to be deceived. If you want to go after your heart, and trust in your heart, you will be deceived. We’ve got to trust in the Word of God and not our heart. Your heart will tell you one thing sometimes, and the Word of God will tell you something else. We can’t follow our heart; we’ve got to follow what the word of God says regardless of how we feel.

This book of the law shall not depart out of thy mouth; but thou shalt meditate therein day and night, that thou mayest observe to do according to all that is written therein: for then thou shalt make thy way prosperous, and then thou shalt have good success. Joshua 1:8

What does the word, meditation, mean? It is like having a tape in your head plays goes over and over. Years ago we had records and record players. When that record player needle would get into a groove, it wouldn’t get out of the groove. What would happen next? The record would play the same thing over and over and over and over. When you’re meditating on the things of God, they need to be going over and over in your mind.

In order for us to keep our heart with all diligence, our meditation has to be on the things of God all day long. Guard your heart.
