According to Jesus, the issue is the inner man. Forbidding to marry, and commanding to abstain from meats, which God hath created to be received with thanksgiving of them which believe and know the truth. And put a knife to thy throat, if thou be a man given to appetite. But the scripture hath concluded all under sin, that the promise by faith of Jesus Christ might be given to them that believe. The entire Biblical system brings us to Jesus .
Nature is content with little, grace with less, but lust with nothing.
