For all that is in the world, the lust of the flesh, the lust of the eyes, and the pride of life, isn't the Father's, but is the world's.
Lust of the flesh ...  All temptations which have their roots in appetites and needs of the body are included in this; but the appetites of the body are not in themselves sinful.  Therefore, "flesh" is used here in "the ethical sense, meaning the old nature of man, or his capacity to do that which is displeasing to God."[44]
