Doing the thing you think you cannot do

“You gain strength, courage, and confidence by every experience in which you really stop to look fear in the face. You must do the thing which you think you cannot do.”
— Eleanor Roosevelt

Scripture

Fear not, for I am with you;
Be not dismayed, for I am your God.
I will strengthen you,
Yes, I will help you,
I will uphold you with My righteous right hand.’   Isaiah 41:10
