Psalm 9:1 NKJV
I will praise You, O Lord, with my whole heart;
I will tell of all Your marvelous works.
Unite My Heart
MY NOTES
“I will praise You, O Lord, with my whole heart; I will tell of all Your marvelous works.” — Psalm 9:1 (NKJV)
David does not ease into this psalm. He starts with a decision. “I will.” Praise here is not a mood that wandered in. It is a holy resolve. Sometimes you have to set your face and bless the Lord even when enemies are still in view. In this song, the foe is already going down, so the praise runs full. Either way, the point is the same: God gets the praise.
The title says this is for the Chief Musician, to the tune of “Death of the Son.” People have guessed Goliath, Nabal, Absalom. The tune name is uncertain. What is not uncertain is the direction of the praise. It goes to the Lord Himself. Be grateful for the people God uses. Then let thanks grow wings and go higher. Intermediate hands are not the destination.
And it has to be the whole heart. Half a heart is no heart. Divided affection is not adoration; it is a split vote. David is not claiming a sinless performance. He is claiming sincerity. Every power he has will be put to this work—mind, memory, voice, will. That is what the New Testament later calls making melody in the heart, not as silent religion, but as the inner life joining the open confession.
Ephesians 5:19 (NKJV)
“speaking to one another in psalms and hymns and spiritual songs, singing and making melody in your heart to the Lord.”
David knew how easily the heart drifts. That is why he prayed elsewhere:
Psalm 86:11 (NKJV)
“Teach me Your way, O Lord; I will walk in Your truth; Unite my heart to fear Your name.”
A united heart can praise. A scattered heart can only offer fragments.
Then comes the part we neglect. “I will tell.” Praise is not only sung upward. It is spoken outward. Remembering what God has done and saying it out loud is worship. Tell the household of faith. Tell it often. And do not treat the story as too holy for ordinary rooms. Even the ungodly should hear how kind the Lord has been. One mercy jogs the memory of a thousand more. Pull one silver link and a long chain comes up with it.
“Marvelous works” is one rich Hebrew idea. It covers the great redemptive miracles, the quieter daily counterparts, and even the hidden glories waiting in Scripture.
Psalm 106:7, 22 (NKJV)
“Our fathers in Egypt did not understand Your wonders; They did not remember the multitude of Your mercies, But rebelled by the sea—the Red Sea.”
…
“Wondrous works in the land of Ham, Awesome things by the Red Sea.”
Forgetting wonders is how rebellion starts. Telling them is how faith stays awake.
Psalm 71:17 (NKJV)
“O God, You have taught me from my youth; And to this day I declare Your wondrous works.”
Psalm 119:18 (NKJV)
“Open my eyes, that I may see Wondrous things from Your law.”
Look at yourself honestly, and you will see why the word “marvelous” fits. Preservation. Forgiveness. Conversion. Deliverance. The keeping of a frail soul through a thousand snares. If God made the world from nothing, that is wonder enough. If He made a new creation in a sinner, that is more startling still. Job was right: the works do not run out.
Job 5:9 (NKJV)
“Who does great things, and unsearchable, Marvelous things without number.”
David could not list every work. Neither can we. “All” means all we know, and then some, because there is always more. Creation. Providence. Redemption. The call out of darkness. The strange survival of grace in a noisy heart. And still ahead: the rising of the dead, the last judgment, the public reign of Christ. Heaven will not get tired of this theme. Surprise and rapture will keep company there.
David later said the same thing in public:
Psalm 111:1 (NKJV)
“Praise the Lord! I will praise the Lord with my whole heart, In the assembly of the upright and in the congregation.”
Notice that David doesn’t keep his gratitude bottled up inside. He tells it forth. True praise is infectious; it reminds the church family of God’s faithfulness and leaves the skeptical world without an excuse.
When you speak openly about how God answered a desperate prayer, brought you through a season of grief, or broke a persistent sin in your life, you build a fortress of faith around your soul. You silence the accusations of the enemy and anchor your trust in the God who never fails.
So praise is duty, and then it becomes privilege. God expects a fitting return from people for whom He has done marvels. Start with one mercy. Let that mercy unlock the rest.
Speak it. Sing it. Do it with the whole heart you have today, and ask Him to unite the rest.
Prayer
Abba Father, You alone are worthy of all my gratitude, honor, and praise. Forgive me for the times I have brought You a divided heart—distracted by the world, weighed down by worry, or quick to credit human effort for what only Your grace accomplished. Unite my heart to fear Your name. Open my eyes to see the endless stream of Your marvelous works in my life—from the gift of salvation to Your quiet daily preservation. Give me the courage to speak openly of Your goodness, so that others may hear and put their trust in You. In the precious name of Jesus, Amen.

Proverb for Today
My son, obey your father’s command, and don’t abandon your mother’s teaching. Bind them always on your heart, tie them around your neck. When you walk, they will lead you; when you lie down, they will watch over you; and when you wake up, they will talk with you. For the mitzvah is a lamp, Torah is light, and reproofs that discipline are the way to life. Proverbs 6:20-23 CJB
(mitzvah=commandment
Torah=Law)
Daily Scripture
But God has revealed them to us through His Spirit. For the Spirit searches all things, yes, the deep things of God. For what man knows the things of a man except the spirit of the man which is in him? Even so no one knows the things of God except the Spirit of God. Now we have received, not the spirit of the world, but the Spirit who is from God, that we might know the things that have been freely given to us by God. 1 Corinthians 2:10-12 NKJV
Closing
“The Lord bless you and keep you; The Lord make His face shine upon you, And be gracious to you; The Lord lift up His countenance upon you, And give you peace.” Numbers 6:24-26 NKJV
Grace be with you. Amen.

Charles Spurgeon
With a holy resolution the songster begins his hymn; I will praise thee, O Lord. It sometimes needs all our determination to face the foe, and bless the Lord in the teeth of his enemies; vowing that whoever else may be silent we will bless his name; here, however, the overthrow of the foe is viewed as complete, and the song flows with sacred fulness of delight. It is our duty to praise the Lord; let us perform it as a privilege. Observe that David’s praise is all given to the Lord. Praise is to be offered to God alone; we may be grateful to the intermediate agent, but our thanks must have long wings and mount aloft to heaven. With my whole heart. Half heart is no heart. I will show forth. There is true praise to the thankful telling forth to others of our heavenly Father’s dealings with us; this is one of the themes upon which the godly should speak often to one another, and it will not be casting pearls before swine if we make even the ungodly hear of the loving-kindness of the Lord to us. All thy marvelous works. Gratitude for one mercy refreshes the memory as to thousands of others. One silver link in the chain draws up a long series of tender remembrances. Here is eternal work for us, for there can be no end to the showing forth of all his deeds of love. If we consider our own sinfulness and nothingness, we must feel that every work of preservation, forgiveness, conversion, deliverance, sanctification, etc., which the Lord has wrought for us, or in us is a marvelous work. Even in heaven, divine loving-kindness will doubtless be as much a theme of surprise as of rapture.

Enduring Word
I will praise You, O LORD, with my whole heart: David recognized that God was worthy of praise with the whole heart. His entire being should be directed in affection toward God. (Guzik)
i. “Half heart is no heart.” (Spurgeon)
ii. “We do not praise God with our lips very much, if at all. And when we do, if we do, we praise him halfheartedly…. It is more often true that Christians complain of how God has been treating them, carry on excessively about their personal needs or desires, or gossip.” (Boice)
I will tell of all Your marvelous works: Here, David described an important and often neglected way to praise God – to tell of all His marvelous works. Simply remembering and telling the great things God has done is a wonderful way to praise Him. (Guzik)
i. “Christians, so called, when they meet, seldom speak about God! Why is this? Because they have nothing to say.” (Clarke)
ii. Marvelous works: “Wonderful deeds (or things) is a single Hebrew word, particularly frequent in the Psalms, used especially of the great redemptive miracles (e.g. Psalm 106:7, 22), but also of their less obvious counterparts in daily experience (cf. Psalm 71:17), and of the hidden glories of Scripture (Psalm 119:18).” (Kidner)
iii. David could see that “Today is as full of God to this man as the sacred yesterdays of national history, and his deliverances as wonderful as those of old.” (Maclaren)

I will praise thee, O Lord — That is, in view of the merciful interpositions referred to in the psalm Psalms 9:3-5, and in view of the attributes of God’s character which had been displayed on that occasion Psalms 9:7-12.
With my whole heart — Not with divided affection, or with partial gratitude. He meant that all his powers should be employed in this service; that he would give utterance to his feelings of gratitude and adoration in the loftiest and purest manner possible.
I will show forth — I will recount or narrate – to wit, in this song of praise.
All thy marvelous works — All his works or doings fitted to excite admiration or wonder. The reference here is particularly to what God had done which had given occasion to this psalm, but still the psalmist designs undoubtedly to connect with this the purpose to give a general expression of praise in view of all that God had done that was fitted to excite such feelings.

I will praise [thee], O Lord, with my whole, heart,…. This is what is called in the New Testament making melody in the heart, or singing with grace in the heart, Ephesians 5:19; and yet does not signify mere mental singing, but vocal singing, the heart joining therein; for the word here used for praise signifies to confess, to speak out, to declare openly the praises of God in the public congregation, as David elsewhere determines to do, Psalm 111:1; the heart ought to, be engaged in every, part of divine service and worship, whether in preaching or in hearing, or in prayer, or in singing of praise; and the whole heart also: sometimes God has nothing of the heart in worship, it is removed far from, him, and gone after other objects; and sometimes it is divided between God and the creature; hence the psalmist prays that God would unite his heart to fear him, and then he should praise him with all his heart, with all that was within him, with all the powers and faculties of his soul; see Psalm 86:11. This phrase is not expressive of the perfection of this duty, or of performing it in such manner as that there would be no imperfection in it, or sin attending it; for good men fail in all their performances, and do nothing good without sin; hence provision is made for the iniquities of holy things; but of the heartiness and sincerity of it; and in such a sincere and upright manner the psalmist determines, in the strength of divine grace, to praise the Lord;
I will show forth all thy marvelous works; such as the creation of all things out of nothing, and the bringing them into the form and order in which they are by the word of God; and in which there is such a display of the power and wisdom of God; and particularly the formation of man out of the dust of the earth, in the image, and after the likeness of God; the sustentation of the whole world of creatures in their being, the providential care of them all, the preservation of man and beast; and especially the work of redemption: it is marvelous that God should think of redeeming sinful men; that he should fix the scheme of it in the way he has; that he should pick upon his own Son to be the Redeemer; that ungodly men, sinners, the chief of sinners, and enemies, should be the persons redeemed; and that not all the individuals of human nature, but some out of every kindred, tongue, people, and nation: as also the work of grace, which is a new creation, and more marvelous than the old; a regeneration, or a being born again, which is astonishing to a natural man, who cannot conceive how this can be; a resurrection from the dead, or a causing dry bones to live; a call of men out of darkness into marvelous light; and it is as wondrous how this work is preserved amidst so many corruptions of the heart, temptations of Satan, and snares of the world, as that it is; to which may be added the wonderful works yet to be done, as the setting up of the kingdom of Christ, the destruction of antichrist, the resurrection of the dead, the last judgment, and the eternal glory and happiness of the saints; and doubtless the psalmist may have respect to the many victories which he, through the divine power, obtained over his enemies; and particularly the marvelous one which was given him over Goliath with a stone and sling: these the psalmist determined to make the subject of his song, to dwell and enlarge upon, to show forth unto others, and to point out the glories, beauties, and excellency of them: and when he says “all” of them, it must be understood of as many of them as were within the compass of his knowledge, and of as much of them as he was acquainted with; for otherwise the marvelous works of God are infinite and without number, Job 5:9.

Matthew Henry
The title of this psalm gives a very uncertain sound concerning the occasion of penning it. It is upon Muth-labben, which some make to refer to the death of Goliath, others of Nabal, others of Absalom; but I incline to think it signifies only some tone, or some musical instrument, to which this psalm was intended to be sung; and that the enemies David is here triumphing in the defeat of are the Philistines, and the other neighboring nations that opposed his settlement in the throne, whom he contested with and subdued in the beginning of his reign, 2 Sa. 5:8.
1. God expects suitable returns of praise from those for whom he has done marvelous works.
2. If we would praise God acceptably, we must praise him in sincerity, with our hearts, and not only with our lips, and be lively and fervent in the duty, with our whole heart.
3. When we give thanks for some one particular mercy we should take occasion thence to remember former mercies and so to show forth all his marvelous works.
