Psalms 71:14

David is here in a holy transport of joy and praise, arising from his faith and hope in God; we have both together Psa 71:14, where there is a sudden and remarkable change of his voice; his fears are all silenced, his hopes raised, and his prayers turned into thanksgivings. "Let my enemies say what they will, to drive me to despair, I will hope continually, hope in all conditions, in the most cloudy and dark day; I will live upon hope and will hope to the end." Since we hope in one that will never fail us, let not our hope in him fail us, and then we shall praise him yet more and more. "The more they reproach me the more closely will I cleave to thee; I will praise thee more and better than ever I have done yet." The longer we live the more expert we should grow in praising God and the more we should abound in it. I will add over and above all thy praise, all the praise I have hitherto offered, for it is all too little. When we have said all we can, to the glory of God's grace, there is still more to be said; it is a subject that can never be exhausted, and therefore we should never grow weary of it. Now observe, in these verses, I. How his heart is established in faith and hope; and it is a good thing that the heart be so established. Observe, 1. What he hopes in, Psa 71:16. (1.) In the power of God: "I will go in the strength of the Lord God, not sit down in despair, but stir up myself to and exert myself in my work and warfare, will go forth and go on, not in any strength of my own, but in God's strength - disclaiming my own sufficiency and depending on him only as all-sufficient - in the strength of his providence and in the strength of his grace." We must always go about God's work in his strength, having our eyes up unto him to work in us both to will and to do. (…

71:14 The psalmist contrasts his own goodness with his enemies’ evil; he centers his life in the Lord, even during hard times (see 9:17-18; 27:13-14).
