A man who is with God is the majority
Charles SpurgeonWhy count heads? A man who is with God is the majority even if there are a thousand on the other side. Sometimes our helpers could be too many for God to work through them, as happened with Gideon, who could do nothing until he had increased his strength by reducing his numbers. But the Lord's army is never too small. When God wanted to found a nation, He called only Abram and blessed him. When he wanted to defeat the haughty Pharaoh, he did not use any army, but only Moses and Aaron. The "one man ministry", as certain sages call it, has been used much more by the Lord than trained groups with their officers. Did all the Israelites together kill as many Philistines as Samson did alone? Saul and his armies smitten his thousands, and David his ten thousands.
The Lord can give the enemy ample advantages and still defeat him. If we have faith, we have God with us, and then what are the multitudes of men? A sheepdog can herd a large flock of sheep. If the Lord sends you, my brother, His strength will achieve His divine purpose. So rest on the promise, and be brave.
