Revelation 3:10b I also will keep you from the hour of trial which shall come upon the whole world, to test those who dwell on the earth.
The Lord commends Philadelphia for keeping His command to persevere, and tells them that in doing so, He will in turn keep them from the hour of trial that will come upon the whole earth. Now this sounds initially like a promise to only certain Christians. “If you do as I command, I will preserve you and not others.” But, as we will see, this promise is for all genuine believers which the church of Philadelphia is.
