Which of the following is a core message of the Book of Daniel?

The core message of the Book of Daniel centers around the sovereignty of God. Throughout the narrative, Daniel and his companions demonstrate unwavering faith in God's power and authority, especially in the face of persecution and adversity. The book illustrates how God is in control of historical events and the rise and fall of empires, exemplified through the stories of Nebuchadnezzar's dreams, the fiery furnace, and the writing on the wall during Belshazzar's feast.

The emphasis on God’s sovereignty serves to encourage the Jewish exiles during a time of oppression, reassuring them that despite their circumstances, God ultimately reigns supreme. This message is portrayed vividly in the apocalyptic visions of the latter chapters, where it is revealed that God's kingdom will ultimately triumph over earthly kingdoms.

While themes like ritual purity, the necessity of sacrifices, and divine punishment are certainly present in the broader context of Old Testament theology, they do not capture the central thrust of the Book of Daniel's narrative and theological emphasis as effectively as the sovereignty of God does.
