The word is ???????, 'animal, sensuous,' in opposition to what is 'spiritual.' It is translated 'natural' in 1Co 2:14; 15:44,46. To be sensual is to be led by the passions of man's flesh: it is placed with 'earthly' and 'devilish' in Jas 3:15; and is contrasted with having the Holy Spirit in Jude 1:19.
But the natural man does not receive the things of the Spirit of God, for they are folly to him; and he cannot know them because they are spiritually discerned;
It is sown a natural body, it is raised a spiritual body: if there is a natural body, there is also a spiritual one.
But that which is spiritual was not first, but that which is natural, then that which is spiritual:
This is not the wisdom which comes down from above, but earthly, natural, devilish.
These are they who set themselves apart, natural men, not having the Spirit.
