In 480 B.C. the outmanned army of Sparta's King Leonidas held off the Persian troops of Xerxes by fighting them one at a time as they came through a narrow mountain pass. Commenting on this strategy, C.H. Sprugeon said, "Suppose Leonidas and his handful of men had gone out into the wide-open plain and attacked the Persians why, they would have died at once, even though they might have fought like lions."

Spurgeon continued by saying that Christians stand in the narrow pass of today. If they choose to battle every difficulty at once, they're sure to suffer defeat. But if they trust God and take their troubles one by one, they will find that their strength is sufficient.
