Saying with a loud voice, Worthy is the Lamb that was slain to {d} receive power, and riches, and wisdom, and strength, and honour, and glory, and blessing.

(d) To have all praise given to him, as to the mightest and wisest

Wesley's Notes

5:12 Worthy is the Lamb - The elders said, Rev 5:9, Worthy art thou. They were more nearly allied to him than the angels. To receive the power, and c. - This sevenfold applause answers the seven seals, of which the four former describe all visible, the latter all invisible, things, made subject to the Lamb. And every one of these seven words bears a resemblance to the seal which it answers.

Jamieson-Fausset-Brown Bible Commentary

12. to receive power-Greek, "the power." The remaining six (the whole being seven, the number for perfection and completeness) are all, as well as "power," ranged under the one Greek article, to mark that they form one complete aggregate belonging to God and His co-equal, the Lamb. Compare Re 7:12, where each of all seven has the article.

riches-both spiritual and earthly.

blessing-ascribed praise: the will on the creature's part, though unaccompanied by the power, to return blessing for blessing conferred [Alford].

Matthew Henry's Concise Commentary

5:8-14 It is matter of joy to all the world, to see that God deals with men in grace and mercy through the Redeemer. He governs the world, not merely as a Creator, but as our Saviour. The harps were instruments of praise; the vials were full of odours, or incense, which signify the prayers of the saints: prayer and praise should always go together. Christ has redeemed his people from the bondage of sin, guilt, and Satan. He has not only purchased liberty for them, but the highest honour and preferment; he made them kings and priests; kings, to rule over their own spirits, and to overcome the world, and the evil one; and he makes them priests; giving them access to himself, and liberty to offer up spiritual sacrifices. What words can more fully declare that Christ is, and ought to be worshipped, equally with the Father, by all creatures, to all eternity! Happy those who shall adore and praise in heaven, and who shall for ever bless the Lamb, who delivered and set them apart for himself by his blood. How worthy art thou, O God, Father, Son, and Holy Ghost, of our highest praises! All creatures should proclaim thy greatness, and adore thy majesty.
