Was Father God ever described as an old man with a beard seated on a throne in Heaven? Here are some references to the idea:

“As I looked, thrones were set in place, and the Ancient of Days took his seat. His clothing was as white as snow; the hair of his head was white like wool. His throne was flaming with fire, and its wheels were all ablaze.” – Daniel 7:9

“The hair of His head was white like wool, as white as snow, and His eyes were like a blazing fire.” – Revelation 1:14

“… and among the lampstands was One like the Son of Man, dressed in a long robe, with a golden sash around His chest. The hair of His head was white like wool, as white as snow, and His eyes were like a blazing fire. His feet were like polished bronze refined in a furnace, and His voice was like the roar of many waters.” – Revelation 1:13-15

These are actually likely references to Jesus after His ascension.
