Galatians 5:16-18 New International Version (NIV)
16 So I say, walk by the Spirit, and you will not gratify the desires of the flesh. 17 For the flesh desires what is contrary to the Spirit, and the Spirit what is contrary to the flesh. They are in conflict with each other, so that you are not to do whatever[a] you want. 18 But if you are led by the Spirit, you are not under the law.
