The human body and its physical needs and desires, esp. as contrasted with the mind or the soul : I have never been one to deny the pleasures of the flesh.
But I say, walk by the Spirit, and do not gratify the desires of the flesh. For the desires of the flesh are against the Spirit, and the desires of the Spirit are against the flesh; for these are opposed to each other, to prevent you from doing what you would. But if you are led by the Spirit you are not under the law. Galatians 5:16-18
