S – As he was getting into the boat, the man who had been demon-possessed begged him earnestly that he might remain with him. ¹⁹ Jesus did not let him but told him, “Go home to your own people, and report to them how much the Lord has done for you and how he has had mercy on you.” ²⁰ So he went out and began to proclaim in the Decapolis how much Jesus had done for him, and they were all amazed. 

Mark 5:18–20 CSB

O – Commentary:

Jesus told him to go to his home (immediate family) and family (lit., “to yours,” your own people) from whom he had been estranged and report to them all that the Lord, the Most High God (cf. 5:7; Luke 8:39) had done for him and how He had shown mercy on him. The man obeyed and began to proclaim (cf. Mark 1:4, 14) in the Decapolis (a league of 10 Gr. cities all but one east of the Jordan) the wonderful things Jesus (cf. “Lord,” 5:19) had done for him. Those who heard him were amazed (ethaumazon, cf. “astonished”; 6:6a; 12:17; 15:5, 44).

Since this man was a Gentile and his preaching activity was confined to a Gentile area where Jesus was not welcome, Jesus did not give His usual injunction to silence 

“Mark,” in The Bible Knowledge Commentary: An Exposition of the Scriptures

A – The transformed man wanted to remain close to Jesus and he was sent back to his own people.  God positioned the man to be most effective.  He was a Gentile and would not be accepted by the Jewish people.  Yet, in his realm used by God to share the good news.  Where are we positioned today to share the gospel with others most effectively?  

R – Heavenly Father, we worship and surrender to you.  Thank you for delivering us from our sin and way of life that does not honor you.  Please help us recognize the opportunities to share the good news with others.  Give us the courage to share authentically and with your heart of compassion.
