Mk.5:19,20. – And he did not permit him but said to him, “Go home to your friends and tell them how much the Lord has done for you, and how he has had mercy on you.” And he went away and began to proclaim in the Decapolis how much Jesus had done for him, and everyone marveled.
I love the story of the demonized man from Gadara and his testimony of redemption. Gadara was near Decapolis, across the Sea of Galilee from Galilee, the region Jesus had lived His whole life and the was the main thrust of His ministry. Reaching this man from Gadara was a foretaste of the incredible harvest of the earth that would begin over the next few years. This was the first fruits of the coming harvest. This tormented soul was tasting acceptance, love, and peace for the first time in his life. Of course he wanted to leave that world and go with Jesus. Jesus had other plans though. Listen to Henry’s thoughts on this passage.
“Christ would not suffer him to go with him, lest it should savor of ostentation, and to let him know that he could both protect and instruct him at a distance. And besides, he had other work for him to do; he must go home to his friends, and tell them what great things the Lord had done for him, the Lord Jesus had done; that Christ might be honored, and his neighbors and friends might be edified, and invited to believe in Christ….The man, in a transport of joy, proclaimed, all the country over, what great things Jesus had done for him. This is a debt we owe both to Christ and to our brethren, that he may be glorified and they edified.”
The plan that the Lord had for this man was “go and tell”. Go tell everybody about what the Lord did for you and tell them about His great mercy. In a matter of a few months Jesus came through Decapolis again. This time rather than being asked to leave a large crowd gathered. Where had the crowd come from? Obviously the testimony of the madman from the tombs in Gadara had effected the whole region, the people wanted to see Jesus for themselves. Jesus healed the sick and fed a crowd of four thousand with a miraculous multiplication of fish and bread. This was Jesus’s venture into the harvest of the earth. Maybe He is still telling those He has delivered to go tell what the Lord has done for you and talk about His great mercy
