This idiom is used in biblical context. The story "The Character of Paul" specifically in Chapter 21: His Trustfullness used this idiom and considered to be the oldest. "...Because Paul is sure of God in Christ, he is. certain of victory. Man can be delivered
from his sins. He does not fight a losing battle. He can be freed from the sense of guilt.
"There is therefore now no condemnation to them that are in Christ Jesus." He knows this
from his own experience..."

Hi billdad!Have been searching the origin of "fight a losing battle" and I haven't found the correct answer yet. I read a quotation "A wise person would retreat when fighting a losing battle; a foolish person would fight until there is nothing left to lose" (Sheila Cheng) by accident and I loved the meaning of this quotation. As my way of sharing, I posted the idiom "fight a losing battle".
