Isaiah prophesies about the Messiah and also the Assyrian invasion with its implications for Assyria and Judah : Isaiah 8−12
Isaiah saw a day when Judah would meet the same fate as Israel: both were to walk so far away from God that he had nothing left to protect from invasion, despite warning them repeatedly.
The Lord gave Isaiah a strong warning not to think like everyone else does. It was timely advice for all who live in fear (then and now):
Isaiah 8:12-14Don’t call everything a conspiracy, like they do,
and don’t live in dread of what frightens them.
Make the Lord of Heaven’s Armies holy in your life.
He is the one you should fear.
He is the one who should make you tremble.
He will keep you safe.
He goes on to explain:
Isaiah 8:16-17 Preserve the teaching of God;
entrust his instructions to those who follow me.
I will wait for the Lord,
who has turned away from the descendants of Jacob.
I will put my hope in him.
