Isaiah 30:25-26

There will also be an abundance of water, even on the hilltops, when the Lord defeats His enemies (at Armageddon; cf. Isaiah 30:19; Isaiah 2:12-17; Isaiah 25:1-5; Revelation 16:16; Revelation 19:17-21). Increased light and the healing of God’s formerly broken and bruised people will also mark "that day" (cf. Isaiah 24:23; Romans 8:21). The point is that things will be much better then than now. It may be impossible for life as we know it to exist if there were literally seven times as much light as there is now. Yet a renovation of nature as well as humankind is in view.

"Evidently [this is] a description of the glories of the Millennium (since this kind of prosperity has no appropriateness for a heavenly existence)." [Note: Archer, p. 630. Cf. Delitzsch, 2:39.]

Young interpreted these blessings as referring to the blessings of salvation. [Note: Young, 2:360-63]
