In the Christian Bible, the term Seven Spirits of God appears four times in the Book of Revelation. The meaning of this term has been interpreted in multiple ways.
The seven Spirits of God are mentioned four times in the Book of Revelation, and in the book of Isaiah it names each Spirit.
In one interpretation, the "Seven Spirits" represent the sevenfold ministry of the Spirit as depicted in the Book of Isaiah. As it is written: "The Spirit of the LORD shall rest upon him, the Spirit of wisdom and understanding, the Spirit of counsel and might, the Spirit of knowledge and of the fear of the LORD, and He will delight in the fear of the Lord." Isaiah 11:2-3 (NASB). Including the Spirit of the Lord, and the Spirits of wisdom, of understanding, of counsel, of might, of knowledge and of fear of the LORD, here are represented the seven Spirits, which are before the throne of God. The reference to the lamb in relates it to the Seven Spirits which first appear in and are associated with Jesus who holds them along with seven stars.
An alternative view is that the seven graces ("charisma") of Romans 12:6-8 reflect the seven spirits of God. The Holy Spirit manifests in humankind through these graces, reflecting the seven spirits of Yahweh. The seven graces are: 1) insight (prophecy); 2) helpfulness (service or ministry); 3) instruction (teaching); 4) encouragement; 5) generosity (giving); 6) guidance (leadership); and 7) compassion. This agrees with Isaiah 11:2-3 if "the Spirit of the Lord" is recognized as categorical and "the delight in the fear of the Lord" is added.
In the New Testament, the Greek term "Dynamis" (translated by some as "Virtues") suggests a class of exalted spiritual beings; perhaps parallel to the "chief Princes" (Sar rishown) in the Old Testament, of which the Archangel Michael is stated to be one (Daniel 10:13). "Dynamis" is used by the Apostle Paul to refer to spiritual beings in Romans 8:38; Ephesians 1:21, 3:10, 6:12; and Colossians 1:16, 2:10 & 15. "Powers and principalities" can apply to both angelic and demonic beings, but more often in the New Testament to demonic beings. However, it should be noted, most modern Protestant translators take "Dynamis" to mean 'strength', 'power' or 'ability', whereas the ancient and modern Catholic conception of activity or power was often understood as 'virtues'.
Others follow this line of thought, though find the connect to "dynamis" referred to by Paul less likely. It is possible that these seven angels are a special entourage charged with special duties by the Lamb, about whom we have little to no specific knowledge.
