He is not white now.
Revelation 1
10 I was in the Spirit on the Lord’s Day, and I heard behind me a loud voice, as of a trumpet, 11 saying, “I am the Alpha and the Omega, the First and the Last,”[f] and, “What you see, write in a book and send it to the seven churches which are in Asia: to Ephesus, to Smyrna, to Pergamos, to Thyatira, to Sardis, to Philadelphia, and to Laodicea.”
12 Then I turned to see the voice that spoke with me. And having turned I saw seven golden lampstands, 13 and in the midst of the seven lampstands One like the Son of Man, clothed with a garment down to the feet and girded about the chest with a golden band. 14 His head and hair were white like wool, as white as snow, and His eyes like a flame of fire; 15 His feet were like
fine brass, as if refined in a furnace, and His voice as the sound of many waters; 16 He had in His right hand seven stars, out of His mouth went a sharp two-edged sword, and His countenance was like the sun shining in its strength. 17 And when I saw Him, I fell at His feet as dead. But He laid His right hand on me, saying to me, “Do not be afraid; I am the First and the Last. 18 I am He who lives, and was dead, and behold, I am alive forevermore. Amen.
He is the color of fine brass, He does have white hair though.
All Praise The Ancient Of Days
