II. Samuel's closing words are tender, wise, and full of great truths. He begins with encouragement blended with reiteration of the people's sin. It is not safe for a forgiven man to forget his sin quickly. The more sure he is that God has forgotten, the more careful he should be to remember it, for gratitude, humility and watchfulness. But it should never loom so large before him as to shut out the sunshine of God's love, for no fruits of goodness will ripen in character without that light. It is a great piece of practical wisdom always to keep one's forgiven sin in mind, and yet not to let it paralyse hopefulness and effort. 'Ye have indeed done all this evil, ... yet turn not aside from following Jehovah.' That is a truly evangelical exhortation. The memory of past failures is never to set the tune for future service. Again, Samuel based the exhortation to whole-hearted service of Jehovah on Jehovah's faithfulness and great benefits (vs. 22-24), It is suicidal folly to turn away from Him who never turns away from us; it is black ingratitude, as well as suicidal folly, to refuse to serve Him whose mercies encompass us. That divine good pleasure, which has no source but in Himself, flows out like an artesian well, unceasing. His 'nature and property' is to love. His past is the prophecy of His future. He will always be what He has been, and always do what He has done. Therefore we need not fear, though we change and are faithless. 'He cannot deny Himself.' His revealed character would be dimmed if He abandoned a soul that clung to Him. So our faith should, in some measure, match His faithfulness, and we should build firmly on the firm foundation.
III. Samuel answers the people's request for his prayers with a wise word, full of affection, and also full of dignity and warning, all the more impressive because veiled. He promises his continued intercession, but he puts it as a duty which he owes to God rather than to them only, and he thus sufficiently asserts his God-appointed office. He promises to do more than pray for them; namely, to continue as their ethical and religious guide, which they had not asked him to be. That at once makes his future position in the monarchy clear. He is still the prophet, though no longer the judge, and, as the future was to show, he has to direct monarch as well as people. But it also hints to the people that his prayers for them will be of little avail unless they listen to his teaching. Whether a Samuel prays for us or not, if we do not listen to the voices that bid us serve God, we 'shall be consumed.'
