Psalms 92:15

This mercy to the aged proves the faithfulness of their God, and leads them to shew that the Lord is upright, by their cheerful testimony to his ceaseless goodness. We do not serve a Master who will run back from his promise. Whoever else may defraud us, he never will. Every aged Christian is a letter of commendation to the immutable fidelity of Jehovah. He is my rock, and there is no unrighteousness in him. Here is the psalmist's own seal and sign manual; still was he building upon his God, and still was the Lord a firm foundation for his trust. For shelter, for defence, for indwelling, for foundation, God is our rock; hitherto he has been to us all that he said he would be, and we may be doubly sure that he will abide the same even unto the end. He has tried us, but he has never allowed us to be tempted above what we are able to bear: he has delayed our reward, but he has never been unrighteous to forget our work of faith and labour of love. He is a friend without fault, a helper without fail. Whatever he may do with us, he is always in the right; his dispensations have no flaw in them, no, not the most minute. He is true and righteous altogether, and so we weave the end of the psalm with its beginning, and make a coronet of it, for the head of our Beloved. It is a good thing to sing praises unto the Lord, for "he is my rock, and there is no unrighteousness in him."

THESE verses occur at the close of a Psalm for the Sabbath over which there rests a Sabbatic glory of perfect calm, of hallowed peace. Amidst the business and bustle of daily life the great trouble of the Psalmist was the prosperity of the wicked, but it does not trouble him at all when he enters the sanctuary to keep the holy day. He then looks upon the ungodly who prosper in the world as so much flowering grass in their beauty and he beholds them cut down and utterly destroyed. And it is meet that a Psalm for the Sabbath should be calm and peaceful, cloudless and far-seeing. If on any day we see things in their right light and our views extend farther than at other times, surely it should be on the day of sacred rest. I know a friend who wished to take a house in Newcastle. It stood on an elevated position and the landlord, who wished to have him for a tenant, took him to the attic of the house and said, "What a view there is from this window! Do you know," he asked, "that on Sundays you can see Durham Cathedral?" "On Sundays!" said my friend, with a look of surprise, "And why not on other days?" "Well," said the landlord, "on Sundays there is less smoke and so you can see farther." And, as it is in the natural world, so it should always be in the spiritual—less of the smoke of this world—less of the dust and the care of life and, therefore, a clearer vision of the things which are beyond—things which God reveals to spiritual eyes! Read and sing this Psalm often and may your heart constantly be in that sweet restful state.

To show that the Lord is upright - Such persons show how faithful God is to his promises, how true to his word, how kind to them who trust in him. He is the Rock, the Fountain, whence all good comes. There is no unrighteousness in him - He does nothing evil, nothing unwise, nothing unkind. He is both just and merciful.

To shew that the Lord is upright - That is, This will be a proof that God is faithful to his promises; that he is the true friend of his people. The fact that they live long - that they are happy and useful even in old age, will be a demonstration that God is the friend of virtue, and that he deals with people according to their character. He is my rock - He is my defense; that which constitutes my security. See the notes at Psa 18:2. This is language of strong confidence in view of all that is said in the psalm. And there is no unrighteousness in him - This is said in the most absolute form - implying the most entire confidence. God is altogether to be trusted. There is no evil or wrong in his character or in his dealings. In all respects he is worthy of confidence: “worthy” to be loved, trusted, adored, obeyed, by the inhabitants of all worlds. What a sublime thought is this! What a consolatory truth! What would the universe be if God, a Being of infinite POWER, were not a Being of perfect RIGHTEOUSNESS, and could not be trusted by the creatures which he has made!
