Ps 57.7: My heart is fixed, O God, my heart is fixed: I will sing and give praise.
Our text finds David in the midst of dire circumstances. His soul is "among lions," and "bowed down." He is surrounded by men who "have dug a pit" for him, "whose teeth are spears and arrows, and their tongue a sharp sword [vv. 4, 6]." And yet he is able to cry to God that his heart is fixed. Marvelous stability! What does it mean experientially to have a heart that is fixed? What can so stabilize our hearts?
Scripture tells us, in Matthew 6, that where our TREASURE is, our HEART will be also. The treasure is the key. Yet we all know the disappointment of finding our hearts drawn off course. "Prone to wander, Lord, I feel it; prone to leave the God I love." Have we not all felt the sorrow of knowing Jesus to be worthy of unfailing devotion and undying love, and finding our affections falling short of the mark and our flesh responding to lesser pulls?
There is help for this condition in the 13th chapter of Matthew, as the Holy Spirit would open up to us the parable of Jesus concerning the man who found a treasure hidden in a field. Notice here that the treasure is hidden. Perhaps it is buried somewhere in the field, as we most often picture. But perhaps it is distributed throughout the soil, as nuggets of gold that must be mined from the earth, or even hidden to the eye, as the powerful treasure of fruitfulness is hidden in the seeds in the ground. Once the treasure is recognized, however, the whole field is bought for joy, even at the price of this man selling "all that he had."
Now this field represents the seemingly nonessential things in our life that we have to go through in order to come to the treasure. Jesus is the treasure; and He is of a different order than the natural order through which we must move in coming to Him. Are we willing, for the excellency of the treasure, to buy the whole field? God doesn't just "plop" Jesus into the midst of circumstances that are always pleasing to us! A field has to be worked -- tilled, cultivated -- in order to gain its yield. This speaks of the crucified life. We have to move through the field, pressing against the world, sowing to the Spirit daily, realizing that we are in the world, but not of it.
This is where Christians need to understand that our coming into possession of the treasure will demand a heart that is fixed! A heart that is absolutely convinced that its real treasure is Jesus, and will be willing to go through whatever is necessary to possess Him. We will find ourselves fainting quickly if there isn't worked into us, by the power of the Holy Ghost, an absolute persuasion that Jesus is worth it all. No natural wisdom, no intellectual endeavors, no amount of study will persuade us of the magnificence of the great treasure which is ours in Christ Jesus. It must come under the power of the Holy Ghost! If our hearts are wandering hearts, going from one thing to another in an effort to attain satisfaction for our being, we need to cry out for the stabilizing, steadying influence of the Holy Spirit, Who will ever do the thing He is best at doing: making the things of Christ real to our hearts. When those things are real, it will be amazing how much extraneous activity will fall by the wayside.
Now on the level of intellectual understanding, of theoretical knowing, none of us has a problem with this; but it is an altogether different thing when this truth actually begins to take hold in our lives. For God doesn't present Himself as Truth in the intellectual realm; He presents Himself as Truth in the inmost part of man: in our hearts, in our flesh-and-blood experiential definition, where we have to work through some things in order to come to Him Who is our treasure. Perhaps we've been inspired by the treasure, and yet nonetheless, the world through which we have to move could still be a trap. If the enemy can succeed in clouding over the vision of the beauty of the treasure that is ours in Christ Jesus, then all too soon we will find the world holding out for us its own beauties. So often we say that all we want is Jesus, but if we are honest, we find that we try to dictate to God the terms in which Jesus will come to us. There is always the danger that the crucifixion required will not be to our liking, and we will settle down. This is why we are admonished to the stirring up of the gift within us.1
Ultimately, our only safety from the enemy's tactics, and the deceitfulness of our own hearts, is to be totally taken over by the Spirit of God. We need God's divine operations, until every area of our mind, every area of our emotions, every stratum of our being is under the influence of Him Who gave Himself for us that we might be made alive unto Him! Then, out of the stability of a heart that is fixed, will be true spontaneity of the Spirit. It will come to pass, what is spoken of in the Scriptures, "The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell whence it cometh, and whither it goeth: so is every one that is born of the Spirit."2 Divine elusiveness is our portion! The enemy will not be able to keep up with us!
Notice the thought that comes immediately after David's testimony that his heart is fixed: "I will sing and give praise." Not, he will sing and then his heart will become fixed! When we can say with David, "My heart is fixed," we will have a joy in the Holy Spirit which we have never yet known. We will cease to dwell on what we are enduring, and will instead be taken up with Him.
If you are at all bogged down over the seemingly non-essential things you are going through, read prayerfully the 32nd chapter of Jeremiah. Ask the Holy Spirit to open up to you the Gospel truths of this prophetic action on the part of Jeremiah, in buying a field. Take in the hopelessness of the prophesied inevitable captivity. Take in the tremendous faith required to purchase a field at God's instruction, when the circumstances contradicted any hope of possessing it. Take in the glorious promise of God, regarding future purchases of fields to follow, showing Jeremiah's act to be but the earnest of a great inheritance. See herein the One Who bought a field at such a great price, for the sake of His Chosen. Consider the risk He took, as the field was infiltrated with the seed of Satan, the tares already sown under his dominion. And now the Spirit answers to the blood, telling us to follow where He has trod. As Jesus bought the field by the shedding of His blood, so we possess God by dispossessing ourselves.
God has a treasure now in the earth, because of Jesus' obedience. Jesus was the first One to buy the truth and sell it not, and now we can come along in His train, buying up, buying up, redeeming the time. As we now take His yoke upon us, putting our hands to the plow, and learn of Him, we will praise Him for the wisdom with which He has chosen to hide the treasure in the field. We will praise Him for the glory which is His in concealing the treasure, and the grace with which He enables us to have the honor of searching it out!3 For there is no limitation in God; He has purchased the whole field. "We're marching through Immanuel's ground!" The way may not be easy, but it is sure.
