And what to make of Ezekiel's wheels?
Now as I beheld the living creatures, behold one wheel upon the earth by the living creatures, with his four faces. The appearance of the wheels and their work was like unto the colour of a beryl: and they four had one likeness: and their appearance and their work was as it were a wheel in the middle of a wheel. When they went, they went upon their four sides: and they turned not when they went. As for their rings, they were so high that they were dreadful; and their rings were full of eyes round about them four. And when the living creatures went, the wheels went by them: and when the living creatures were lifted up from the earth, the wheels were lifted up. Whithersoever the spirit was to go, they went, thither was their spirit to go; and the wheels were lifted up over against them: for the spirit of the living creature was in the wheels. When those went, these went; and when those stood, these stood; and when those were lifted up from the earth, the wheels were lifted up over against them: for the spirit of the living creature was in the wheels.
- Ezekiel 1:15-21 (KJV)
Are they UFOs?
No sorry. They are a metaphor for something else.
As the wheel like complications were under the guidance of the hand beneath the wings of the cherubim, so the complicated play of human events is under divine control. Amidst the strife and tumult of nations, He that sitteth above the cherubim still guides the affairs of the earth.
- Ellen White, Education 178.1
His plan that every part of His work shall depend on every other part, as a wheel within a wheel, all acting in harmony. The humblest worker, moved by the Holy Spirit, will touch invisible chords, whose vibrations will ring to the ends of the earth, and make melody through eternal ages.
- Ellen White, The Desire of Ages, p. 823
