Does a Christian have enemies outside of the world, the flesh, and the devil? An often repeated phrase I hear is that &quot;The enemies of the Christian are world, the flesh, and the devil.&quot; But I wonder, does God's word reveal to us that there are more enemies than those 3 that we should be wary of?
The phrase above is not a phrase in the bible but it's no doubt passed around because it's easy to remember and poignantly true. I just wonder if there's explicitly more than that.
Below are some verses identifying the hurdles of the world, the flesh, and the devil--but I wonder if there is anything else that we must fight against.
World:


James 4:4 NIV You adulterous people, don’t you know that friendship with the world means enmity against God? Therefore, anyone who chooses to be a friend of the world becomes an enemy of God.

Romans 12:2 NIV Do not conform to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what God’s will is—his good, pleasing and perfect will.



Flesh:


Galatians 5:13 NIV You, my brothers and sisters, were called to be free. But do not use your freedom to indulge the flesh; rather, serve one another humbly in love.

Galatians 6:7-8 NIV Do not be deceived: God cannot be mocked. A man reaps what he sows. Whoever sows to please their flesh, from the flesh will reap destruction; whoever sows to please the Spirit, from the Spirit will reap eternal life.

Romans 7:25 ESV Thanks be to God through Jesus Christ our Lord! So then, I myself serve the law of God with my mind, but with my flesh I serve the law of sin.



Devil:


1 Peter 5:8 NIV Be alert and of sober mind. Your enemy the devil prowls around like a roaring lion looking for someone to devour.
Ephesians 6:11 ESV Put on the whole armor of God, that you may be able to stand against the schemes of the devil.
The phrase in question comes from the Book of Common Prayer, from the Litany.

FROM all evil and mischief; from sin; from the crafts and assaults of the devil; from thy wrath, and from everlasting damnation,    Good Lord, deliver us.
From all blindness of heart; from pride, vainglory, and hypocrisy; from envy, hatred, and malice, and all uncharitableness,    Good Lord, deliver us.
From all inordinate and sinful affections; and from all the deceits of the world, the flesh, and the devil, Good Lord, deliver us.
From lightning and tempest; from earthquake, fire, and flood; from plague, pestilence, and famine; from battle and murder, and from sudden death, Good Lord, deliver us.

The first edition of the Book of Common Prayer was published in 1549, and being the first church service in English, it had a profound impact on English religious phraseology.  Its also where &quot;till death do us part&quot; comes from.
It might be an interesting exercise, I suppose, to go through the list of things there and cross-reference with a Bible concordance.
