This verse is part of a vision given to John, the author of the book of Revelation, in which he sees a vast multitude of people from every nation, tribe, and language standing before the throne of God in heaven. This verse expresses the worship and praise of this multitude to God, who is described as the source of all blessings, glory, wisdom, thanksgiving, honor, power, and might.
The verse highlights the centrality of God in the worship of the redeemed in heaven and underscores the importance of giving him the glory and honor that is due to him. It also underscores the eternal nature of God's sovereignty, power, and might, which are emphasized in the phrase "for ever and ever."
It serves as a reminder of the ultimate destination of believers, who will one day stand before the throne of God and join the multitude in offering worship and praise to him. It also serves as an encouragement for believers to live their lives in a manner that is worthy of God's kingdom and to direct their worship and praise toward him.
