The description of angelic movement Ezekiel saw in Ezekiel 1:1-28 clearly describes what angelic lights, their associated movement, their ability to change direction, and their amazing speed can look like to us.
However, also for today, keep in mind who is “The Great Deceiver”, and that Scripture warns of how he “will appear as an angel of light”, and will deceive most of the people in the world. Eventually he will empower “The anti-Christ” to even perform humanly impossible “signs and wonders”.
Also, “If it were possible, he [satan] would deceive even the Elect.”
Additionally, the Bible teaches, demonic activity and deception will be greatly increased near/around the “end times”.
The Bible is the best book ever.
