You are forgiven and your fear is understandable. Just remember what Jesus said, "And Lo, I am with you always, even to the end of the age."
And as our President reminded us two weeks ago, "Yea, though I walk through the valley of the shadow of death I will fear no evil for Thou art with me."
The U.S. may or may not be there in the book of Revelation.
But you are, with all the saints.
Shalom.
Fear is a useful emotion, which would be foolish to ignore. It heightens your awareness to danger and the need to defend yourself. It is only a problem when it is irrational.
Think carefully about how you really feel. Make that strong emotion work 'for' you just as you do the love with which God has armed you for this day.
