Deliver us from evil

Revelation 3:10 “I also will keep [tereo] you from [ek] the hour of trial [temptation]…”

I can’t say with certainty that the ‘hour of trial’ is the great tribulation, but even if it is, the deliverance may not be necessarily a physical one, especially since such a great multitude of Christians will go through it:  Revelation 12.17; 13.7; 7.9-14.  

It may be a spiritual kind of deliverance.

Compare this with John 17:15 “I do not pray that you should take them out of the world, but that you should keep [tereo] them from [ek] the evil [ponerou].

This kind of keeping sounds like the Lord’s prayer: “deliver us from the evil [ponerou].  The keeping from the “hour” in Rev 3.10 may be the same idea and be of a spiritual kind (not a physical kind, since many believers will be put to death during the great tribulation, Rev6.9-11).
