David had enjoyed the mercy of God from his very birth. We are apt to forget the tender care of God over our infancy, but we ought to remember it: and it will be a great comfort to us, if we come to a second childhood, to remember how kindly God took care of us in the first.
Psalms 71:7-11. I am at a wonder unto many, but thou art my strong refuge. Let my mouth be filled with thy praise and with thy honour all the day. Cast me not off in the time of old age; forsake me not when my strength faileth. For mine enemies speak against me, and they that lay wait for my soul take counsel together, saying, God hath forsaken him: persecute and take him; for there it none to deliver him.
Surely that ought to have been the reason for letting him alone. With right-minded persons it would have been so, but the devil and his children are arrant onwards, and their argument is, “Persecute and take him: for there is none to deliver him.” You might as well expect tenderness in a wolf as anything like bravery and chivalry in a persecutor.
Psalms 71:12-14. O God be not far from me: O my God, make haste for my hell. Let them be confounded and consumed that are adversaries to my soul; let them be covered with reproach and dishonour that seek my hurt. But I will hope continually, and will yet raise thee more and more.
How was he going to do it? Already his mouth was filled with God’s praise, so, surely, he would fill his whole life with it, and his actions which would speak more loudly than his words, should bear daily testimony to the goodness of God.
Psalms 71:15-16. My mouth shall shew forth thy righteousness and thy salvation all the day; for I know not the numbers thereof. I will go in the strength of the Lord God:-“
This shall be my praise; my very movements, my goings, my progress shall be in the ‘strength of the Lord God’”
Psalms 71:16-17. I will make mention of thy righteousness, even of thine only. O God, thou hast taught me from my youth.
Here is the same kind of argument again: “ O Lord, I went to school to thee, so I must teach others what thou hast taught me.”
Psalms 71:17. And hitherto have I declared thy wondrous works.
“Thou madest me a preacher, and I have stuck to my word. Hitherto have I declared thy wondrous works.’”
Psalms 71:18-20. Now also when I am old and grayheaded, O God, forsake me not; until I have shewed thy strength unto this generation and thy power to every one that is to come. Thy righteousness also, O God, is very high, who hast done great things: O God, who is like unto thee! Thou, which hast shewed me great and sore troubles, shalt quicken me again,
“Thou shalt not merely deliver me from my great and sore troubles, but thou shalt give me more life, thou ‘Shalt quicken me again.’” Divine quickening is the best remedy for a troubled heart.
Psalms 71:20. And shalt bring me up again from the depths of the earth.
“Though I seem to be like a man buried in the depth of the earth thou wilt bring me up again.”
Psalms 71:21-22. Thou shalt increase my greatness, and comfort me on every side. I will also praise thee-
God blessing us, and we in return blessing him, so it ought to be. The more God does for us, the more we ought to do for him, is it not so, brother? Is not this good argument? Art thou carrying it out? Let thy conscience answer.
Psalms 71:22-23. With the psaltery, even thy truth, O my God: unto thee will I sing with the harp. O thou Holy One of Israel. My lips shall greatly rejoice when I sing unto thee.
Singing unto God ought to be the gladdest of exercises, when it is done in a doleful, dolorous way, it is not singing, but groaning.
Psalms 71:23. And my soul, which thou hast redeemed.
“The sprinkled blood is on my soul, and therefore it shall leap for joy. Rescued from captivity, bought back from slavery, “my soul, which thou hast redeemed; shall greatly rejoice when I sing unto thee.”
Psalms 71:24. My tongue also shall talk of thy righteousness all the day long: for they are confounded, for they are brought unto shame, that seek my hurt.
