It is not a sin to have a body, to have natural appetites, but it is a sin to refuse to sacrifice them at the word of God. Satan’s first fundamental outguards are in the innocence of nature. We say, “But it cannot be wrong to have a little sympathy here, a little curiosity there”; the Bible lifts the veil just enough to show there is a great supernatural force behind that entices for one purpose, to get us away from obeying God’s voice.
