Verse 15. - He shall call upon me, and I will answer him. This is equivalent to, "Whenever he calls upon me, I will answer him," or "I will grant all his prayers." I will be with him in trouble (comp. Psalm 46:1). I will deliver him (see above, ver. 14). And honour him; or, "bring him to honour" (compare "I will set him on high," in the preceding verse).

91:9-16 Whatever happens, nothing shall hurt the believer; though trouble and affliction befal, it shall come, not for his hurt, but for good, though for the present it be not joyous but grievous. Those who rightly know God, will set their love upon him. They by prayer constantly call upon him. His promise is, that he will in due time deliver the believer out of trouble, and in the mean time be with him in trouble. The Lord will manage all his worldly concerns, and preserve his life on earth, so long as it shall be good for him. For encouragement in this he looks unto Jesus. He shall live long enough; till he has done the work he was sent into this world for, and is ready for heaven. Who would wish to live a day longer than God has some work to do, either by him or upon him? A man may die young, yet be satisfied with living. But a wicked man is not satisfied even with long life. At length the believer's conflict ends; he has done for ever with trouble, sin, and temptation.He shall call upon me, and I will answer him,.... God is to be invoked by prayer, and to be called upon in every time of trouble, in faith and with fervency, in truth and uprightness, and sincerity of soul; and he himself directs and encourages to it, and promises an answer, which he always sooner or later gives; for he is a God hearing and answering prayer; see Psalm 50:15.

I will be with him in trouble; the Lord knows his people in adversity; he visits them in their affliction, grants his gracious presence with them, supports them under it, that they are not overwhelmed by it; he bears them up and through it, and makes all things work together for their good:

I will deliver him, and honour him: deliverance is again promised, to denote the certainty of it; and with this addition, that the Lord will honour such that know him, and love him: all his saints are honoured by him, by taking them into his family, and giving them a name better than that of sons and daughters of the greatest potentate; by clothing them with the righteousness of his Son; by adorning them with the graces of his Spirit; by granting them communion and fellowship with himself, and by bringing them to his kingdom and glory.
