The young man couldn't see the celestial horses until the LORD opened his eyes?
II Kings 6:17 And Elisha prayed, and said, LORD, I pray thee, open his eyes, that he may see. And the LORD opened the eyes of the young man; and he saw: and, behold, the mountain was full of horses and chariots of fire round about Elisha.
So, will it be similar for these horses?Will only the ones whose eyes the LORD opens, will be able to see them?
Revelation 9:17 And thus I saw the horses in the vision, and them that sat on them, having breastplates of fire, and of jacinth, and brimstone: and the heads of the horses were as the heads of lions; and out of their mouths issued fire and smoke and brimstone.18 By these three was the third part of men killed, by the fire, and by the smoke, and by the brimstone, which issued out of their mouths.19 For their power is in their mouth, and in their tails: for their tails were like unto serpents, and had heads, and with them they do hurt.
