Of course that passage in Isaiah is someone great. I said I was scared, which I still am but the answers there in the passage...

¹ But now, this is what the LORD says—
he who created you, O Jacob,
he who formed you, O Israel:
"Fear not, for I have redeemed you;
I have summoned you by name; you are mine.

² When you pass through the waters,
I will be with you;
and when you pass through the rivers,
they will not sweep over you.
When you walk through the fire,
you will not be burned;
the flames will not set you ablaze.
