Serve the Lord with faith

Judges 7:1-14
Before the war between Israel and Medianites, the Lord let Gideon reduce his army number from twenty-two thousand men to three hundred men. In order that Israel may not boast against God that their own strength has saved them.
Gideon went to the camp of Medianites as God told him, he heard the talk in the camp, Gideon knew that the Lord has bring the enemy into his hand.
Bedouin from the east - the Midianties who were descendants of Abraham by his second wife, Keturah - swept through southern Israel as far as the Philistines city of Gaza. The terror spread by these fierce camel-rider is vividly pictured in 6:11. Gideon is forces to thresh his meagre grain harvest secretly, in the confines of the wine press.
The faith of this man, for all his initial caution, is see in his readiness to face the Midianite hordes(成群) with a force of only 300 men.
The barley loaf stands for Israel, the tent for the nomadic(游牧) Midianites
Why?
God don't want the people serve him are trembles, without faith. The behavior is not good are excludes from the servant of the Lord either, who drink water like the dogs.
Those who scoop up the water and lap it from their hands are more alert to danger than those who kneel.
How?
Serve the Lord with faith and live as noble. For we are the servant of the Almighty God.
