~He gives freedom

2 Corinthians 3:17b

"Where the Spirit of the Lord is, there is liberty."

There is no bondage in Jesus Christ, only freedom. He is the essence of freedom. Until you surrender your will over to Him, you will not know freedom. Maybe you have though. You've given your life to Jesus Christ, but deep down inside you know there are still areas you don't have victory in. If there are, you need to call it what it is. (That little bad word) Its sin. It needs repented of and given to Jesus.
One problem. Its not always that easy. 
Why? 
Because you are taking back ground that Satan had control over. He never gives up anything without a fight. Rebuking him and sending him away is the next step. And praise God He gives you the power to do it!
But remember the parable Jesus told in Luke 11 about the unclean spirit that was senyt out of a man? It wandered around in barren places looking for rest but not finding any, it decided to return to the man. What a surprise it found when it came back! Everything had been swept and cleaned! So the spirit went and got 7 other spirits more wicked that himself. So it ends that the last state of the man was worse than the first.
Then what's to be done?
The man's fault was in the fact that he did not refill the place that the spirit had been in. When something bad is gotten rid of it needs replaced by something good.
The key then is to beg God to fill the emptiness in your life and to close the doors that Satan has used to gain entrance in.

"These things have I spoken unto you, that in me ye might have peace. In the world ye shall have tribulation: but be of good cheer; I have overcome the world."

~John 16:33
