Psalm 71:16

I will go in the strength of the Lord GOD: I will make mention of thy righteousness, even of thine only.

I will go in the strength of the Lord God,.... Go on praising him, as he had determined to do in the preceding verses; not in his own strength, knowing that his heart was not always disposed aright or prepared and fit for such service; and that though the daily continuance of favours required constant praise, yet he needed always the aids of divine grace to raise his affection and song: or "I will go into the strengths of the Lord God" {d}; the power of God is expressed in the plural number, to show the greatness of it, which is as a garrison to the believer; see 1 Peter 1:5; a strong hold, a strong tower, a strong habitation, as in Psalms 71:3; into which he goes by faith, and is there safe, in all times of distress and danger: or the sense is, that he would go into the house of God, the temple and sanctuary, and in his strength perform the duties of public worship there; and it may include all religious actions, private and public, and every, spiritual undertaking; which ought to be attempted and performed, not in our own strength, but in the strength of the Lord: man is become, through sin, a weak and impotent creature; though he is very hard to be brought to a sense and acknowledgment of his weakness; true believers are sensible of it, and own it; and such, knowing that there is a sufficiency of strength in Christ for them, look and go to him for it; to do otherwise, to attempt to do anything in our own strength, betrays our weakness, folly, and vanity, and is dangerous, attended with bad consequences, and never succeeds well: the Apostle Peter is an instance of this, Matthew 26:33;

I will make mention of thy righteousness, even of thine only; and that before the Lord himself: not his own righteousness, which he knew would not justify him in his sight, nor render him acceptable to him; nor furnish out a plea or argument why he should receive any favour from him; and therefore resolves not to mention it; but the righteousness of Christ, which is the righteousness of God, which he approves of, accepts, and imputes. This is a pure, perfect, and spotless righteousness, which God is well pleased with; honours his law, satisfies his justice, and so justifies in his sight; and renders person and service acceptable to him; and therefore with great pleasure and boldness, may be mentioned unto as it should be to Christ himself also; by ascribing it to him, as the author of it; by expressing a desire to be found in it; to have faith of interest in it, and joy on account of it; and by owning him openly and freely as the Lord our righteousness: and we should make mention of it to others, in praise of it; extolling it as the righteousness of God, and not a creature; and so sufficient to justify many, even all the seed of Israel; as the best robe of righteousness, better than the best of man's, better than Adam's in innocence, or than the angels' in heaven; as a law honouring and justice satisfying one, and as an everlasting one. And we should put ourselves in mind of it, and, by repeated acts of faith, put it on as our justifying righteousness; since much of our joy, peace, and comfort, depend upon it. And this, and this only, is to be made mention of; it is only in the Lord that there is righteousness: as there is salvation in him, and in no other, so there is righteousness in him, and in no other; wherefore no other is to be mentioned along with it: justification is not partly by Christ's righteousness, and partly by our own; but only by his, and through faith in it; see Romans 9:32.
