To be a Christian is a miraculous change from not being one. The Holy Spirit comes to live inside of us, and He begins to change the way we think and live.

Romans 12 says

 1 Therefore, I urge you, brothers, in view of God's mercy, to offer your bodies as living sacrifices, holy and pleasing to God--this is your spiritual act of worship.
 2 Do not conform any longer to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what God's will is--his good, pleasing and perfect will.

We need to give ourselves to Him in order to allow Him to live in us.
