Galatians 5:16-18 NIV
So I say, walk by the Spirit, and you will not gratify the desires of the flesh. 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 you want. But if you are led by the Spirit, you are not under the law.

Romans 8:13 NIV
For if you live according to the flesh, you will die; but if by the Spirit you put to death the misdeeds of the body, you will live.
