Albert Barnes Commentary Psalms 91:15

"He shall call upon me, and I will answer him; I will be with him in trouble: I will deliver him, and honor him." — Psalms 91:15 (ASV)

He shall call upon me — He shall have the privilege of calling on me in prayer; and he will do it.

And I will answer him — I will regard his supplications, and will grant his requests. There could be no greater privilege — no more precious promise — than this.

I will be with him in trouble — I will stand by him; I will not forsake him.

I will deliver him, and honor him — I will not only rescue him from danger, but I will exalt him to honor. I will recognize him as my friend, and will regard and treat him as such. On earth he shall be treated as my friend; in another world he shall be exalted to honor among the redeemed, and become the associate of holy beings forever.
