It is said that when a prophet's words come true, one will know that he is a true prophet. I am so glad Isaiah was correct and will continue to be correct as the future unfolds.

Isaiah 25:8-9
He will swallow up death forever,

And the Lord God will wipe away tears from all faces;
The rebuke of His people
He will take away from all the earth;
For the Lord has spoken.

And it will be said in that day:
“Behold, this is our God;
We have waited for Him, and He will save us.
This is the Lord;
We have waited for Him;
We will be glad and rejoice in His salvation.”
