What the Bible says about God Riding on a Cloud
(From Forerunner Commentary)

Ezekiel 1:4 The “gleaming metal” (many translations render it “glowing metal”) may be a reference to Christ, the God riding the cloud. Compare the description of Christ's feet at Revelation 1:15: “His feet [were] like unto brilliant metal as if they burned in a furnace” (Jubilee Bible 2000).
