Yes, Revolutionary War was epic.
You mention a whole bunch of backward steps, but there was the notable battle of Trenton, plus many small ones, within the sea of British victories. Even small positive steps has the function of maintaining the spirits to campaign onward.
Yup. Until Trenton, our strategy was “RETREAT” “RUN FOR YOUR LIVES...” Our rag-tag militia-army was all but done for and BUT FOR the Divine Providence of God Almighty, they would have been done for.
We must have the same reliance on the Divine Providence of God Almighty who is for us in this fight today.
