Spurgeon's Treasury of David
The Lord will perfect that which concerneth me. All my interests are safe in Jehovah's hands.
"The work which his goodness began,
The arm of his strength will complete;
His promise is yea and Amen,
And never was forfeited yet."
God is concerned in all that concerns his servants. He will see to it that none of their precious things shall fail of completion; their life, their strength, their hopes, their graces, their pilgrimage, shall each and all be perfected. Jehovah himself will see to this and therefore it is most sure. Thy mercy, O Lord, endureth for ever. The refrain of the former Psalm is in his ears, and he repeats it as his own personal conviction and consolation. The first clause of the verse is the assurance of faith, and this second one reaches to the full assurance of understanding. God's work in us will abide unto perfection because God's mercy towards us thus abideth. Forsake not the works of thine own hands. Our confidence does not cause us to live without prayer, but encourages us to pray all more. Since we have it written upon our hearts that God will perfect his work in us, and we see it also written in Scripture that his mercy changeth not, with holy earnestness entreat that we may not be forsaken. If there be anything good in us, it is the work Of God's own hands: will he leave it? Why has he wrought so much in us if he means to give us up?-it will be a sheer effort. He who has gone so far will surely persevere with us to the end. Our hope for the final perseverance of the believer lies in the final perseverance of believer's God. If the Lord begins to build, and does not finish, it will not be his honour. He will have a desire to the work of his hands, for he knows it has cost him already, and he will not throw away a vessel upon which he has expended so much of labour and skill. Therefore do we praise him with our, whole heart, even in the presence of those who depart from his Holy Word, and, set up another God and another gospel; which are not another, but there be some that trouble us.
John Gill
On Psalms 138:8
The Lord will perfect that which concerneth me,.... Or "will", or "may the Lord perform for me" (x): all things in providence; all that he had appointed for him, that would be for his good and his own glory, Psalm 57:2; and particularly what concerned him as a king. He had made him king over the house of Judah; he had begun to fulfil his promise concerning the kingdom; and he would perfect it, by setting him over all the tribes of Israel. Also he believed he would perfect what concerned him as a saint, even the good work of grace upon his heart; which is but a begun work, is imperfect, is gradually carried on, and will be completed; God is able to do it, and none can hinder him; he has promised to do it, and he is faithful who will do it; and his glory is concerned in it; and it may be depended on it will be finished; he is a rock, and his work is perfect; see Philippians 1:6;
thy mercy, O Lord, endureth for ever; a phrase often used by the psalmist, with which his heart was affected; and here used, both as an argument by which he concluded God would perfect his begun work, and as an encouragement to make the following request:
forsake not the works of thine own hands; as are all the works of providence and grace: the work of grace upon the heart may be expressed in the plural number, because of the several branches of it; which are all so many works, as the work of faith, labour, of love, &c. 1 Thessalonians 1:3; and which is the Lord's handiwork; and a curious work it is, a new creation work, a work of almighty power; and which he will never cease from, or be remiss in, as the word (y) signifies, until he has accomplished it, 2 Thessalonians 1:11. It is a prayer of faith, and may be most confidently believed: and some indeed render it as an expression of faith, "thou wilt not forsake the works of thine hands" (z); David himself was the work of God's hands, as Kimchi observes, as a creature, as a king, and as a saint; and so are all the people of God, Isaiah 45:11; and whom he will never leave nor forsake; for they are his church, his chosen, his children, his portion and inheritance, Psalm 94:14.

Keil & Delitzsch
On Psalms 138:7-8
Out of these experiences-so important for all mankind - of David, who has been exalted by passing through humiliation, there arise from him confident hopes concerning the future. The beginning of this strophe calls Psa 23:4 to mind. Though his way may lead through the midst of heart - oppressing trouble, Jahve will loose these bands of death and quicken him afresh (חיּה as in Psa 30:4; Psa 71:20, and frequently). Though his enemies may rage, Jahve will stretch forth His hand threateningly and tranquillizingly over their wrath, and His right hand will save him. ימינך is the subject according to Psa 139:10 and other passages, and not (for why should it be supposed to be this?) accus. instrumenti (vid., Psa 60:7). In Psa 138:8 יגמר is intended just as in Psa 57:3 : the word begun He will carry out, ἐπιτελεῖν (Phi 1:6); and בּעדי (according to its meaning, properly: covering me) is the same as עלי in that passage (cf. Psa 13:6; 142:8). The pledge of this completion is Jahve's everlasting mercy, which will not rest until the promise is become perfect truth and reality. Thus, therefore, He will not leave, forsake the works of His hands (vid., Psa 90:16.), i.e., as Hengstenberg correctly explains, everything that He has hitherto accomplished for David, from his deliverance out of the hands of Saul down to the bestowment of the promise - He will not let one of His works stand still, and least of all one that has been so gloriously begun. הרפּה (whence תּרף) signifies to slacken, to leave slack, i.e., leave uncarried out, to leave to itself, as in Neh 6:3. אל expresses a negation with a measure of inward excitement.
Matthew Henry
On Psalms 138:6-8
David here comforts himself with three things: -
I. The favour God bears to his humble people (Psa 138:6): Though the Lord be high, and neither needs any of his creatures nor can be benefited by them, yet has he respect unto the lowly, smiles upon them as well pleased with them, overlooks heaven and earth to cast a gracious look upon them (Isa 57:15; Isa 66:1), and, sooner or later, he will put honour upon them, while he knows the proud afar off, knows them, but disowns them and rejects them, how proudly soever they pretend to his favour. Dr. Hammond makes this to be the sum of that gospel which the kings of the earth shall hear and welcome - that penitent sinners shall be accepted of God, but the impenitent cast out; witness the instance of the Pharisee and the publican, Lu. 18.
II. The care God takes of his afflicted oppressed people, Psa 138:7. David, though a great and good man, expects to walk in the midst of trouble, but encourages himself with hope, 1. That God would comfort him: "When my spirit is ready to sink and fail, thou shalt revive me, and make me easy and cheerful under my troubles." Divine consolations have enough in them to revive us even when we walk in the midst of troubles and are ready to die away for fear. 2. That he would protect him, and plead his cause: "Thou shalt stretch forth thy hand, though not against my enemies to destroy them, yet against the wrath of my enemies, to restrain that and set bounds to it." 3. That he would in due time work deliverance for him: Thy right hand shall save me. As he has one hand to stretch out against his enemies, so he has another to save his own people. Christ is the right hand of the Lord, that shall save all those who serve him.
III. The assurance we have that whatever good work God has begun in and for his people he will perform it (Psa 138:8): The Lord will perfect that which concerns me, 1. That which is most needful for me; and he knows best what is so. We are careful and cumbered about many things that do not concern us, but he knows what are the things that really are of consequence to us (Mat 6:32) and he will order them for the best. 2. That which we are most concerned about. Every good man is most concerned about his duty to God and his happiness in God, that the former may be faithfully done and the latter effectually secured; and if indeed these are the things that our hearts are most upon, and concerning which we are most solicitous, there is a good work begun in us, and he that has begun it will perfect it, we may be confident he will, Phi 1:6. Observe, (1.) What ground the psalmist builds this confidence upon: Thy mercy, O Lord! endures for ever. This he had made very much the matter of his praise (Psa 13:6), and therefore he could here with the more assurance make it the matter of his hope. For, if we give God the glory of his mercy, we may take to ourselves the comfort of it. Our hopes that we shall persevere must be founded, not upon our own strength, for that will fail us, but upon the mercy of God, for that will not fail. It is well pleaded, "Lord, thy mercy endures for ever; let me be for ever a monument of it." (2.) What use he makes of this confidence; it does not supersede, but quicken prayer; he turns his expectation into a petition: "Forsake not, do not let go, the work of thy own hands. Lord, I am the work of thy own hands, my soul is so, do not forsake me; my concerns are so, do not lay by thy care of them." Whatever good there is in us it is the work of God's own hands; he works in us both to will and to do; it will fail if he forsake it; but his glory, as Jehovah, a perfecting God, is so much concerned in the progress of it to the end that we may in faith pray, "Lord, do not forsake it." Whom he loves he loves to the end; and, as for God, his work is perfect.
