Psalm 91 is one of sixteen Psalms that are called Messianic Psalms; they are prophetic Psalms revealing the Messiah (Christ) to come. Psalms 2, 8, and 22 are three that you may know.
“And he showed me a pure river of water of life, clear as crystal, proceeding from the throne of God and of the Lamb. In the middle of its street, and on either side of the river, was the tree of life, which bore twelve fruits, each tree yielding its fruit every month. And the leaves of the tree were for the healing of the nations. And there shall be no more curse, but the throne of God and of the Lamb shall be in it, and His servants shall serve Him. They shall see His face, and His name shall be on their foreheads. And there shall be no night there: They need no lamp nor light of the sun, for the Lord God gives them light. And they shall reign forever and ever. Then he said to me, ‘These words are faithful and true.’ And the Lord God of the holy prophets sent His angel to show His servants the things which must shortly take place. ‘Behold, I am coming quickly! Blessed is he who keeps the words of the prophecy of this book.’ Now I, John, saw and heard these things. And when I heard and saw, I fell down to worship before the feet of the angel who showed me these things. Then he said to me, ‘See that you do not do that. For I am your fellow servant, and of your brethren the prophets, and of those who keep the words of this book. Worship God.’ And he said to me, ‘Do not seal the words of the prophecy of this book, for the time is at hand. He who is unjust, let him be unjust still; he who is filthy, let him be filthy still; he who is righteous, let him be righteous still; he who is holy, let him be holy still.’” Revelation 22:1-11.
“My brethren, do not hold the faith of our Lord Jesus Christ, the Lord of glory, with partiality. For if there should come into your assembly a man with gold rings, in fine apparel, and there should also come in a poor man in filthy clothes, and you pay attention to the one wearing the fine clothes and say to him, ‘You sit here in a good place,’ and say to the poor man, ‘You stand there,’ or, ‘Sit here at my footstool,’ have you not shown partiality among yourselves, and become judges with evil thoughts? Listen, my beloved brethren: Has God not chosen the poor of this world to be rich in faith and heirs of the kingdom which He promised to those who love Him? But you have dishonored the poor man. Do not the rich oppress you and drag you into the courts? Do they not blaspheme that noble name by which you are called?” James 2:1-7.
