THE WORD “QUICKLY” HERE IN REV. 22:12 DOES NOT MEAN “SHORTLY” OR “IMMEDIATELY”.“ There are many scoffers who say “Jesus said He would come quickly, but it has been two thousand years and He still hasn’t come.”
However, the idea here is that when Jesus comes, everything will happen quickly. Paul said that it will happen “in a moment, I the twinkling of an eye” (1 Cor.15:52). When the time is right, things will happen quickly. It will be an instantaneous transformation.
