Paul said in Romans 6:13-14, "And do not present your members as instruments of unrighteousness to sin, but present yourselves to God as being alive from the dead, and your members as instruments of righteousness to God. (14) For sin shall not have dominion over you, for you are not under law but under grace."
The question before us is, "Is it possible for a person to be set free and yet still live like their in jail?" The answer is, "Yes, it is." Christians do it all of the time.
There is a story of two brothers who fought for the right to rule over a dukedom in what is now Belgium. The elder brother’s name was Raynald, but he was commonly called “Crassus,” a Latin nickname meaning “fat,” for he was horribly obese. After a heated battle, Raynald’s younger brother Edward led a successful revolt against him and assumed the title of Duke over his lands. But instead of killing Raynald, Edward devised a curious imprisonment. He had a room in the castle built around “Crassus,” a room with only one door. The door was not locked, the windows were not barred, and Edward promised Raynald that he could regain his land and his title any time that he wanted to. All he would have to do is leave the room of his imprisonment. The obstacle to freedom was not in the doors or the windows, but with Raynald himself. Being grossly overweight, he could not fit through the door, even though it was of near-normal size. All Raynald needed to do was diet down to a smaller size, then walk out a free man, with all he had before his fall. However, his younger brother kept sending him an assortment of tasty foods, and Raynald’s desire to be free never won out over his desire to eat. Some would accuse Duke Edward of being cruel to his older brother, but he would simply reply, “My brother is not a prisoner. He may leave when he so wills.”
That is an awesome illustration of what most Christian’s experience. They have indeed been set free, but because of their appetites, they live in defeat. Let that not be the case with us!
