Saying with a loud voice, Worthy is the Lamb that was slain - See the notes on Revelation 5:2, Revelation 5:9. The idea here is, that the fact that he was slain, or was made a sacrifice for sin, was the ground or reason for what is here ascribed to him. Compare the notes on Revelation 5:5.
To receive power - Power or authority to rule over all things. Compare notes on Matthew 28:18. The meaning here is, that he was worthy that these things should be ascribed to him, or to be addressed and acknowledged as possessing them. A part of these things were his in virtue of his very nature - as wisdom, glory, riches; a part were conferred on him as the result of his work - as the mediatorial dominion over the universe, the honor resulting from his work, etc. In view of all that he was, and of all that he has done, he is here spoken of as “worthy” of all these things.
And riches - Abundance. That is, he is worthy that whatever contributes to honor, and glory, and happiness, should be conferred on him in abundance. Himself the original proprietor of all things, it is fit that he should be recognized as such; and having performed the work which he has, it is proper that whatever may be made to contribute to his honor should be regarded as his.
And wisdom - That he should be esteemed as eminently wise; that is, that as the result of the work which he has accomplished, he should be regarded as having ability to choose the best ends and the best means to accomplish them. The feeling here referred to is what arises from the contemplation of the work of salvation by the Redeemer, as a work eminently characterized by wisdom - wisdom manifested in meeting the evils of the fall; in honoring the law; in showing that mercy is consistent with justice; and in adapting the whole plan to the character and needs of man. If wisdom was anywhere demanded, it was in reconciling a lost world to God; if it has been anywhere displayed, it has been in the arrangements for that work, and in its execution by the Redeemer. See the notes on 1 Corinthians 1:24; compare Matthew 13:54; Luke 2:40, Luke 2:52; 1 Corinthians 1:20-21, 1 Corinthians 1:30; Ephesians 1:8; Ephesians 3:10.
And strength - Ability to accomplish his purposes. That is, it is meet that he should be regarded as having such ability. This strength or power was manifested in overcoming the great enemy of man; in his control of winds, and storms, and diseases, and devils; in triumphing over death; in saving his people.
And honor - He should be esteemed and treated with honor for what he has done.
And glory - This word refers to a higher ascription of praise than the word honor. Perhaps that might refer to the honor which we feel in our hearts; this to the expression of that by the language of praise.
And blessing - Everything which would express the desire that he might be happy, honored, and adored. To bless one is to desire that he may have happiness and prosperity; that he may be successful, respected, and honored. To bless God, or to ascribe blessing to him, is that state where the heart is full of love and gratitude, and where it desires that he may be everywhere honored, loved, and obeyed as he should be. The words here express the wish that the universe would ascribe to the Redeemer all honor, and that he might be everywhere loved and adored.
