Bro. Mark Brown begins a new study today in the Gospel of Mark. He labeled this sermon his "Intro to the Intro" of Mark's Gospel. In this sermon we get some background information on this young man...his relationship to Peter and to the Apostle Paul. We will see his growth from the point he abandoned Paul on his first missionary journey(which eventually led to the split between Paul & Barnabas), to the point where Paul specifically asks him to join him in serving Jesus together.
