How does Leadership for Christians look like in 21st Century?

We often hear from the pulpit how important it is for fathers to act as role models for our children so they can grow up to be strong leaders for tomorrow. While this may be true, and logically sound, it is interesting to read that "Those who study leadership tell us that the lack of a strong father figure is a commonplace in the backgrounds of great leaders" (Lewis, 200). These great leaders include William Wilberforce, Shaftsbury, George Whitefield, John Wesley, Charles Wesley, Charles Simeon and William Carey, to name a few. Could it be the lack of father figure caused these men to over-compensate by becoming the powerful leader that they were?
