V.5 The Lord shall destroy the unbelieving nations of the West. Not all at once, for we have read in Daniel how He is going to deal with one group at a time. Russia will be the last (Ezek. 38-39). The last of this verse is interesting. 1 Thessalonians 4:14 refers to the same event (“E” on your chart).
V.6-7 Turn to Isaiah 39:26. It would seem that it is referring to the same future day when the Lord shall return with all us believers, to reign over the earth (“E” on your chart). The light apparently will be much brighter than it is now.
V.8 Two rivers will start to flow out of Jerusalem. It is the only capital in the world without a river. One will flow West into the Mediterranean, the other East, into the Dead Sea.
V.9 Beautiful to read this slowly.
V.14 Think of what a day that will be when this verse is fulfilled.
V.20-21 No one will spoil that wonderful day of “HOLINESS UNTO THE LORD.”
