Gideon was faced with his own weakness, fear and failure when God proclaimed him as a mighty man of valor! Gideon certainly seemed the most unliked to save anyone from the midianites. in spite of Gideon's own personal view of himself, God had a great vision and plan for him.
When God calls Gideon into battle the odds were not in his favor. God then make his army smaller and how he chooses the army is strange. He chooses the most undignified and thirsty.
God is calling us to be his army. To be thirsty enough to not care what others do or think. To be obedient enough to not question His plans or strategy. Unwavering faith and radical obedience is required to see breakthrough and to see God do the impossible.
