Is “Pastor” A Biblical Title for Church Leaders?

The English word "pastor" today is most often used in front of a person's name as a title of someone in a leadership position within a church or religious organization. But is this common title used so often in modern culture really biblical? Would believers in Jesus Christ in the First Century, among whom are the writers of the New Testament portion of the Bible, have used this term as a title, representing leaders and authorities? Who will follow the one true Pastor Jesus, who is the rightful owner of the one true flock, and tend to his sheep under his leadership? Who will pray in faith with the power and authority of Jesus to affect true healing for the multitudes that are suffering in the 21st century? Who will deal with the disease and effects of sin and receive the forgiveness from Jesus that cleanses and heals?
