He is described by John as such:
"His head and his hairs were white like wool, as white as snow; and His eyes were as a flame of fire;
And His feet like unto fine brass, as if they burned in a furnace" (Revelation 1:14-15).
Centuries earlier, Daniel saw the preincarnate Word and noted:
"His body also was like the beryl,
and His face as the appearance of lightning,
and His eyes as lamps of fire,
and His arms and His feet like in color to polished brass"
(Daniel 10:6).
*All of us would do well to "see" our Lord this way when we seek His face in prayer."
