Psalms 89:52

They have blasphemed the change of Christ; but what dost thou answer? "The blessing of the Lord for evermore. Amen and Amen" [Psalm 89:52]. Thanks to His mercy, thanks to His grace. We express our thanks: we do not give them, nor return them, nor repay them: we express our thanks in words, while in fact we retain our sense of them. He saved us for no reward, He heeded not our impieties: He searched us out when we searched not for Him, He found, redeemed, emancipated us from the bondage of the devil and the power of his wicked angels: He drew us to Him to purify us by that faith, from which He releases those enemies only who believe not, and who for that reason cannot be purified. Let those who still remain infidels say every day what they choose; day by day they shall be fewer and fewer that remain; let them revile, mock, accuse, not the death, but the change of Christ. Do they not see that, when they say these things, they fail in purpose either by believing or by dying? For their curse is temporal: but the blessing of the Lord "for evermore." To confirm that blessing is added, "Amen and Amen." This is the signature of the bond of God. Secure then of His promises, let us believe the past, recognise the present, hope for the future. Let not the enemy lead us astray from the way, that He, who gathers us like chickens under His wings, may foster us: lest we stray from His wings, and the hawk of the air carry us off while yet unfledged. For the Christian ought not to hope in himself: if he hopes to be strong, let him be reared by his mother's warmth. This is the hen who gathers her young together; whence is the reproach of our Saviour against the unbelieving Jerusalem. […]

But if you ask how these things come about, ask grace, not doctrine; desire, not understanding; the groaning of prayer, not the study of reading; the Bridegroom, not the master; God, not man; darkness, not clarity; not light, but the fire that wholly inflames and …

Blessed - Let thine enemies reproach thee and thy promises concerning the sending of the Messiah, I will heartily bless and praise thee for them, and encourage myself with them.

Blessed be the Lord for evermore,....

Blessed be the Lord for evermore - Let him treat us as he will, his name deserves eternal praises: our affliction, though great, is less than we have deserved. This verse concludes the Third Book of the Psalter; and, I think, has been added by a later hand, in order to make this distinction, as every Masoretic Bible has something of this kind at the end of each book. The verse is wanting in one of Kennicott’s and one of De Rossi’s MSS.; in another it is written without points, to show that it does not belong to the text, and in three others it is written separately from the text. It is found, however, in all the ancient Versions. The Chaldee finishes thus: “Blessed be the name of the Lord in this world. Amen and Amen. Blessed be the name of the Lord in the world to come. Amen and Amen.” And the reader will find no difficulty to subscribe his Amen, so be it.
