The miracle of the healing of the Officials son shows that Jesus has authority over distance. He is Lord over all of creation, He has no need to be present and healing can take place anywhere that God so chooses. By faith, when we pray, we should take time to listen to what God is saying, perhaps one day He will ask you to pray into a situation you know nothing about. When He does, and you see the results, you will be both amazed and encouraged.
