Where does greatness begin?
Every believer's life is a spiritual journey represented by the lesson he or she needs to follow in order to rule and reign with Christ. You can learn about your own spiritual journey by looking at various characters in Scripture.
David lived in four different places in his lifetime: Bethlehem, Adullam, Hebron, and Zion. Each of these cities represented a specific lesson that you as a believer must learn in order to rule and reign with Christ. Even Jesus had to journey between Bethlehem and the right hand of the Father. He was not born on a throne, but in a manger.
There was a process that carried Jesus and David into authority, and you are subject to that same process. God is more interested in your character than your comfort, and if you submit yourself to this process you will build a strong character that leads to maturity in Christ!
