What prerequisites are needed for successful leadership? Good communicator? Solid character? Leadership ability?

While I realize choosing one prerequisite for leadership can be subjective, I have learned over the years the main prerequisite needed is a relationship with God.

Leaders often fail when attempting to go it alone.
Leaders blindly falter when leading from a humanistic worldview.
Leaders suffer needlessly because they seek help from worldly wisdom.

Only with the guidance, strength, and help of the Almighty God can we lead with this foundational prerequisite for successful leadership. Do we know Him?
