Why can the demonic realm "not touch us"?

To answer this question it is best to examine two key verses in the Bible -1 John 4:4 & 1 John 5:18. I have quoted four different Bible versions viz. NIV, KJV, AMP & MSG for in-depth understanding.


 1 John 4:4You, dear children, are from God and have overcome them, because the one who is in you is greater than the one who is in the world. (NIV)

 Ye are of God, little children, and have overcome them: because greater is he that is in you, than he that is in the world. (KJV)

 Little children, you are of God [you belong to Him] and have [already] defeated and overcome them [the agents of the antichrist], because He Who lives in you is greater (mightier) than he who is in the world. (AMP)

 My dear children, you come from God and belong to God. You have already won a big victory over those false teachers, for the Spirit in you is far stronger than anything in the world. These people belong to the Christ-denying world. They talk the world's language and the world eats it up. But we come from God and belong to God. Anyone who knows God understands us and listens. The person who has nothing to do with God will, of course, not listen to us. This is another test for telling the Spirit of Truth from the spirit of deception. (1 John 4:4-6 MSG)

The above verse makes it clear that those who are in Christ have victory over the demonic realm.

 1 John 5:18 We know that anyone born of God does not continue to sin; the one who was born of God keeps him safe, and the evil one cannot harm him. (NIV)

 We know that whosoever is born of God sinneth not; but he that is begotten of God keepeth himself, and that wicked one toucheth him not. (KJV)

 We know [absolutely] that anyone born of God does not [deliberately and knowingly] practice committing sin, but the One Who was begotten of God carefully watches over and protects him [Christ's divine presence within him preserves him against the evil], and the wicked one does not lay hold (get a grip) on him or touch [him]. (AMP)

 We know that none of the God-begotten makes a practice of sin—fatal sin. The God-begotten are also the God-protected. The Evil One can't lay a hand on them. We know that we are held firm by God; it's only the people of the world who continue in the grip of the Evil One. And we know that the Son of God came so we could recognize and understand the truth of God—what a gift!—and we are living in the Truth itself, in God's Son, Jesus Christ. This Jesus is both True God and Real Life. Dear children, be on guard against all clever facsimiles. (1 John 5:18-21MSG)

So if we have victory over the demonic realm, how can it overcome or “touch us”? Dear beloved in Christ it can not!
