Apocalypse Explained #241
241. Verse 18. I counsel thee, signifies the means of reformation of those who are in the doctrine of faith alone. This is evident from what now follows, for the reformation of those who are in that doctrine is now treated of; therefore "I counsel thee" implies precepts as to how such must live that they may be reformed and thus saved.
Isaiah 10:20-23
20
It will come to pass in that day that the remnant of Israel, and those who have escaped from the house of Jacob will no more again lean on him who struck them, but shall lean on Yahweh, the Holy One of Israel, in truth.
21
A remnant will return, even the remnant of Jacob, to the mighty God.
22
For though your people, Israel, are like the sand of the sea, only a remnant of them will return. A destruction is determined, overflowing with righteousness.
23
For the Lord, Yahweh of Armies, will make a full end, and that determined, in the midst of all the earth.
