Mark 5:17 And they began to beg Jesus to depart from their region. (ESV)
A strange reaction to this exorcism! People fear the supernatural, even if the result is good. People don’t want someone coming in and upsetting the status quo – even when that norm is a crazed demoniac who breaks free 
from chains and cuts himself. Here in ch. 5 (incl. from 4:35) we see themes of fear, faith and Jesus’ authority. The disciples fear the storm, the Gerasene demoniac is a pretty scary guy, and it’s pretty scary when your servants come and tell you your daughter is dead (5:36). In contrast Jesus urges the disciples to have faith (4:40), tells the woman with the issue of blood that her faith has made her well (5:34), and comforts Jairus “Do not fear, only believe” (5:36). Why? Jesus has authority over the storm, over the demons (no matter how many), and He quickly takes charge of the chaos at Jairus’ house and brings wholeness, peace.
So yeah, we needn’t fear. Many are the circumstances of our lives. Yet our Savior who also reigns as King holds the universe in his Hands sustaining it (Col. 1:17) and giving us our next breath. So yes, He asks us to have faith. He is asking us to trust in Him. In our lives and in mission: “I give you authority” (Lk. 10:19).
Lord Jesus, teach me how to live in Your kingdom – in this time between the ages. Teach me how to trust in, cling to, and rely on You – placing all of my hope, faith in You, in Your person, in Your authority. You are good and Your mercy endures forever. Come Lord Jesus, bring Your kingdom – in my house, my home, my family, Your world.
In Jesus’ name – Amen,
Son
