An enemy to God

Mosiah 3: 19
19 For the natural man is an enemy to God, and has been from the fall of Adam, and will be, forever and ever, unless he yields to the enticings of the Holy Spirit, and putteth off the natural man and becometh a saint through the atonement of Christ the Lord, and becometh as a child, submissive, meek, humble, patient, full of love, willing to submit to all things which the Lord seeth fit to inflict upon him, even as a child doth submit to his father.

I have been reading this scripture all my life and never really settled on this phrase before. Enemy is such a strong word. It really makes you think. Being a "natural" man makes you an enemy to God.

Here are two more scriptures that include the same phrase:

Mosiah 16: 5
5 But remember that he that persists in his own carnal nature, and goes on in the ways of sin and rebellion against God, remaineth in his fallen state and the devil hath all power over him. Therefore he is as though there was no redemption made, being an enemy to God; and also is the devil an enemy to God.

Mosiah 2: 38
38 Therefore if that man repenteth not, and remaineth and dieth an enemy to God, the demands of divine justice do awaken his immortal soul to a lively sense of his own guilt, which doth cause him to shrink from the presence of the Lord, and doth fill his breast with guilt, and pain, and anguish, which is like an unquenchable fire, whose flame ascendeth up forever and ever.

Just thinking about the word enemy and what it means. Interesting that Satan is referred to twice.
