Read Mt 8.28-34, Mk 5.1-20, Lk 8.26-39
Jesus heals the demoniac and refuses anymore personal discipleship. He simply tells him to go share his testimony. How important is it for a disciple to have a testimony about what Jesus has done in their lives? This is Discipleship 101. What has Jesus done in your life? Can you make a list of 20, 50, maybe 100 things He has done for you? Can you communicate this in a way that others understand and can follow Jesus as a result of your testimony? Remember this young follower of Christ received virtually no training and yet he completely obeys his new Master. Share the great things Jesus has done for you and you will be well on your way to becoming a fisher of men (Mt 4.19).

Side note: Jesus tells the man to go and tell of the great things “God” has done for him (Lk 8.39 or Lord in Mk 5.19). He immediately goes out and tells people the great things “Jesus” had done for him (Mk 5.20, Lk 8.39). The Gospel writers demonstrate their understanding of the deity of Christ.
