When my oldest daughter was in 8th grade, our church youth group took a missions trip to Atlanta, Georgia. I volunteered to be a chaperone - and we spent a week in

The people of Gerasene were much like the Atlanta Ney sayers. They had heard that Jesus had healed the demon-possessed man and when they came to see - they found it was true. The man was there - in his right mind - standing with Jesus. Instead of trying to find out what it was that Jesus had done, why the demons had left the man, they asked Him to leave.
When the people of Atlanta said "no", we didn't chase them into the streets and throw the sandwiches and flyers into their open windows, pelting them with chicken and buns - we just wished them a good day and they went on their way.
Jesus didn't argue with the Gerasene people, He didn't beg them to let Him stay, didn't threaten to put the demons back - He simply left. One of the gifts that God gives us is free will. We have the option to choose whether or not we will believe who Jesus is and accept it to be true. We can have faith in His promise and stand firm in the fact that if we choose to follow Him, we will, one day, meet Him face to face and it will be more glorious than we can imagine. We can also choose to not believe in Jesus. When faced with the marvel of His creation, the majesty of the earth He made, the peace that passes all understanding, we can simply choose to ignore Him and, in essence, asking Him to leave. But He will be waiting, always waiting, for you to ask Him to come in.
