Final answer:
John saw the Spirit descending from heaven like the creatures in his biblical vision, representing power and glory.
Step-by-step explanation:
The question is asking about what John saw the Spirit descending from heaven like. The Bible provides descriptions of heavenly visions and symbols, such as the one in Revelation 4:2-7, where John describes seeing a throne in heaven and four creatures resembling a lion, a calf, a man, and an eagle. These descriptions are meant to convey a sense of awe and majesty. So, John saw the Spirit descending from heaven like the creatures in his vision, representing power and glory.
