His greatest tool was his desire for and communication with God. Without listening to God, He would not have been able to lead Israel, and would have never known the next step!
Psalm 119:11 says "Your word is a lamp to my feet and a light to my path."As leaders, we need to have enough faith that the next step is all we need to know. We need the courage to take that next step and trust God! We must be listening to God, and intentionally seeking Him.
A good leader has the courage to stand out front, believes God in the next step and boldly asks his people to follow him. A great leader though, knows that the key is not courage and boldness, it is faith! 11:111:6 Faith sets the great leaders apart from the good leaders.
