Why count heads? One man with God is a majority though there be a thousand on the other side. Sometimes our helpers may be too many for God to work with them, as was the case with Gideon, who could do nothing till he had increased his forces by thinning out their numbers. But the Lord’s hosts are never too few. When God would found a nation, He called Abram alone and blessed him. When He would vanquish proud Pharaoh, He used no armies, but only Moses and Aaron. The “one-man ministry,” as certain wise men call it, has been far more used of the Lord than trained bands with their officers. Did all the Israelites together slay so many as Samson alone? Saul and his hosts slew their thousands but David his ten thousands.
The Lord can give the enemy long odds and yet vanquish him. If we have faith, we have God with us, and what are multitudes of men? One shepherd’s dog can drive before him a flock of sheep. If the Lord sent thee, O my brother, His strength will accomplish His divine purpose. Wherefore, rely on the promise, and be very courageous.
