A disciple according to Lord Jesus

Where can we find the best source of understanding of what a disciple is? Not from Webster’s Dictionary, books of popular authors, or even word studies from several scriptures. Only Lord Jesus is the only accurate source of information about what a disciple is — by His dealings with and stories of the followers he called, taught, lived with, and gave Himself to. So this presentation is the result of a serious study and preaching from the Gospel according to Mark.
