The sermon teaches that Psalm 138:8 is a promise for true believers: the Lord will complete what He has begun in them. Christian assurance rests entirely on God’s mercy and Christ’s redeeming work, not on human merit, strength, or the quality of faith. Spurgeon distinguishes genuine confidence from presumptuous assurance by insisting that true faith produces prayer, repentance, good works, and diligent ministry. The appropriate response is personal trust in the promise, continual pleading that God will not forsake His work, and active hope for the spread of the gospel.
Theological center: God sovereignly completes the salvation of His people by enduring mercy grounded in Christ’s cross, while genuine assurance produces prayerful obedience rather than presumption.
Applications: Examine your spiritual concern · Place confidence in the Lord · Believe God will perfect His people · Abandon presumptuous, prayerless living

“The LORD will perfect that which concerneth me: thy mercy, O LORD, endureth for ever: forsake not the works of thine own hands.” Psalm 138:8 I HAVE selected this text, or rather it has been given to me to furnish a motto for the whole year to all the believing family of God now present. It was brought under my notice from a very dear friend, a venerable minister of the Church of England, and an earnest lover of the truth as it is in Jesus, who always sends me, at the beginning of the year, or a day or two previously, a little envelope sealed up, that I am not to open till New Year’s day, containing a printed text of Scripture, which he desires to be preserved during the remainder of the year, to act as a staff whereon we may rest through the pilgrimage of the next twelve months. When I opened my envelope, I found this text and it charmed me. It contains in itself the very essence of the grace of God. It reads like music to the soul, and is like a bottle of water in the desert to the thirsty lip. Let me read it again, and remember it, and dwell upon it, and digest it, during all the year. “The LORD will perfect that which concerneth me. Thy mercies, O LORD, endureth for ever: forsake not the works of thine own hands.” In the opening, I must remark that this is not the heritage of all mankind. The word “me” in the text, cannot be appropriated by any man, unless he in some respects, resembles the character of David, who penned this psalm. The text however, itself is its own guard. If you look at it, you will see that there is in its heart a full description of a true Christian. I will ask you three questions suggested by the words themselves, and according to your answer to these three questions, shall be my reply, yes or no, as to whether this promise belongs to you. To begin, let us read the first sentence—“The LORD will perfect that which concerneth me.” Now, have you a concern in and a concern about heavenly things? Have you ever felt that eternity concerns you more than time, that the mansions of heaven are more worthy your consideration than the dwelling places of earth? Have you felt that you ought to have a greater concern about your immortal soul than about your perishing body? Remember, if you are living the life of the butterfly, the life of the present, a sportive and flowery life, without making any preparation or taking any thought for a future world, this promise is not yours. If the things of God do not concern you, then God will not perfect them for you. You must have in your own soul a concern about these things, and afterwards you must…
