David Castles preaches on John Mark, the writer of the gospel of Mark, and the companion of Paul. Converted through the preaching of Peter, with a godly mother in Mary, John Mark went from failure to fruitfulness as a servant of God. He then wrote a gospel about the “perfect servant”, the Lord Jesus Christ! The unique features of Mark’s gospel are also helpfully spelt out in this message (Message preached 30th Apr 2015)
