I know, I‘m not supposed to inject God into the discussion, but sometimes it helps to know WHAT GOD HAS DONE IN SOME PAST, SIMILARLY HOPELESS SITUATIONS FOR HIS PEOPLE:
When the overwhelming number of enemies was gathered to attack His people, he sent the enemy terrifying dreams to cause the enemy to lose heart and run away. Another time when the enemy had joined forces with other peoples to attack his people, GOD CAUSED THEM TO MISTRUST , SUSPECT AND ACTUALLY ATTACK THEIR OWN ALLIES LEAVING MOST ALL OF THEM DEAD OR RETREATING FROM THE BATTLE THAT OMITTED ATTACKING HIS PEOPLE ! Another time he told a handful of his people to surround the massive camp of the enemy at night, after they were asleep, as if they too were a massive force and to light bright fires and beat drums loudly, screamin as if ready to attack, and the massive enemy force panicked and ran away with none of Gods people harmed. He has sent RUMORS and false “visions” among the enemy, dividing and driving them to panic.
So, we have to take courage from his power and faithfulness.
