PSALM 71: Psalm for Old Age

PSALM 71:

Cast me not off in the time of old age;

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.

vs.9,18

"This psalm to God expresses the concerns of old age. 

At a time in his life when he thinks he should be exempt from certain

kinds of troubles, he once again is personally attacked....This psalm is clearly the prayer of an elderly man threatened by his enemies (verses 9, 18). 

Before expressing his petition proper, the psalmist first states a brief introduction to his petition (verses 1-4).
He reinforces these words with a marvelous statement of his lifelong trust in the Lord (verses 5-8).

This section is rich with expression of trust and communion with God: “Thou are my hope” (verse 5), “Thou art my trust" (verse 5), “Thou are He” (verse 6).

I. Confidence in God Stated (71:1-8)
In Thee, O LORD, do I put my trust... vs.1
II. Confidence in God Practiced in Prayer (71:9-13).
O God, be not far from me.. vs.12
III. Confidence in God Vindicated (71:14-24).
Thy righteousness also, O God, is very high, who hast done great things: O God, who is like unto Thee! vs.19

David prays that he might never be made ashamed of dependence upon God.

It was in David's old age that the rebellion of Absalom took place."
BooksOfTheBible/ChrlesSpurgeon

By Thee have I been holden up from the womb:

Thou art He that took me out of my mother's bowels:

my praise shall be continually of Thee.

vs.6
