Psalms 91:15

15. He shall call upon me. He now shows more clearly what was meant by trusting in God, or placing our love and delight in him. For that affection and desire which is produced by faith, prompts us to call upon his name. This is another proof in support of the truth, which I had occasion to touch upon formerly, that prayer is properly grounded upon the word of God. We are not at liberty in this matter, to follow the suggestions of our own mind or will, but must seek God only in so far as he has in the first place invited us to approach him. The context, too, may teach us, that faith is not idle or inoperative, and that one test, by which we ought to try those who look for Divine deliverances, is, whether they have recourse to God in a right manner. We are taught the additional lesson, that believers will never be exempt from troubles and embarrassments. God does not promise them a life of ease and luxury, but deliverance from their tribulations. Mention is made of his glorifying them, intimating that the deliverance which God extends, and which has been spoken of in this psalm, is not of a mere temporary nature, but will issue at last in their being advanced to perfect happiness. He puts much honor upon them in the world, and glorifies himself in them conspicuously, but it is not till the completion of their course that he affords them ground for triumph. It may seem strange that length of days should be mentioned in the last verse as promised to them, since many of the Lord’s people are soon taken out of the world. But I may repeat an observation which has been elsewhere made, that those Divine blessings which are promised in relation to the present perishing world, are not to be considered as made good in a universal and absolute sense, or fulfilled in all according to one set and equal rule. Wealth and other worldly comforts must be looked upon as affording some experience of the Divine favor or goodness, but it does not follow that the poor are objects of the Divine displeasure; soundness of body and good health are blessings from God, but we must not conceive on this account that he regards with disapprobation the weak and the infirm. Long life is to be classed among benefits of this kind, and would be bestowed by God upon all his children, were it not for their advantage that they should be taken early out of the world. They are more satisfied with the short period during which they live than the wicked, though their life should be extended for thousands of years. The expression cannot apply to the wicked, that they are satisfied with length of days; for however long they live, the thirst of their desires continues to be unquenched. It is life, and nothing more, which they riot in with such eagerness; nor can they be said to have had one moment’s enjoyment of that Divine favor and goodness which alone can communicate true satisfaction. The Psalmist might therefore with propriety state it as a privilege peculiarly belonging to the Lord’s people, that they are satisfied with life. The brief appointed term is reckoned by them to be sufficient, abundantly sufficient. Besides, longevity is never to be compared with eternity. The salvation of God extends far beyond the narrow boundary of earthly existence; and it is to this, whether we live or come to die, that we should principally look. It is with such a view that the Psalmist, after stating all the other benefits which God bestows, adds this as a last clause, that when he has followed them with his fatherly goodness throughout their lives, he at last shows them his salvation.
