Final answer:
The question refers to the Christian belief in the second coming of Jesus Christ, who is prophesied to return in a cloud with power and great glory.
Step-by-step explanation:
The question "Whom will people see coming in a cloud with power and great glory?" references a figure commonly associated with Christian eschatology or religious texts, particularly in the context of the second coming of Jesus Christ. This image and belief stem from passages in the Christian Bible where it is prophesied that Jesus will return in a cloud with power and great glory. This event is anticipated by many Christians as a time of judgment and the fulfillment of God's promise to bring about a new era. The arrival is often depicted in religious artwork and literature, symbolizing hope, salvation, and divine intervention for believers.
