undeniable that the doctrine invented by the Papists, which divides the work of perseverance in holiness between man's free will and God's grace, 595 precipitates wretched souls into destruction.
Psalm 71:17-19
17. O God! thou hast taught me from my youth; and hitherto will I announce thy wondrous works. 18. And still, O God! when I am old and grey-headed, forsake me not, until I declare thy strength to the generation, and thy power to all who are to come. 19. And thy righteousness, O God! Is very high: for thou hast done great things: O God! who is like thee?
17. O God! thou hast taught me from my youth. The Psalmist again declares the great obligations under which he lay to God for his goodness, not only with the view of encouraging himself to gratitude, but also of exciting himself to continue cherishing hope for the time to come: which will appear from the following verse. Besides, since God teaches us both by words and deeds, it is certain that the second species of teaching is here referred to, the idea conveyed being, that David had learned by continual experience, even from his infancy, that nothing is better than to lean exclusively upon the true God. That he may never be deprived of this practical truth, he testifies that he had made great proficiency in it. When he promises to become a publisher of God's wondrous works, his object in coming under this engagement is, that by his ingratitude he may not interrupt the course of the Divine beneficence.
Upon the truth here stated, he rests the prayer which he presents in the 18th verse, that he may not be forgotten in his old age. His reasoning is this: Since thou, O God! hast from the commencement of my existence given me such abundant proofs of thy goodness, wilt thou not stretch forth thy hand to succor me, when now thou seest me decaying through the influence of old age? And, indeed, the conclusion is altogether inevitable, that as God vouchsafed to love us when we were infants, and embraced us with his favor when we were children, and has continued without intermission to do us good during the whole course of our life, he cannot but persevere in acting toward us in the same way even to the end. Accordingly, the particle ,גםgam, which we have translated still, here signifies therefore; it being David's design, from the consideration that the goodness of God can never be exhausted, and that he is not mutable like men, to draw the inference that he will be the same towards his people in their old age, that he was towards them in their childhood. He next supports his prayer by another argument, which is, that if he should fail or faint in his old age, the grace of
That is, which represents this work as performed, partly by God, and partly by a power which man has in himself underived from God.
