When we talk or write he can obviously know what we are communicating. So by writing things down, especially our plans, do you think this gives him more opportunities to disrupt our path to God? To drive a wedge into our lives separating us from who we seek? I've never heard of any Christians talking about this yet we are told repeatedly he is Prince of this world, at least for a while, so why wouldn't he use everything at his disposal to draw us into Hell with him?
Seems like his power has already been limited.
Matthew 4:8-9 Again, the devil taketh Him up into an exceeding high mountain, and sheweth Him
all the kingdoms of the world, and the glory of them;[9] And saith unto Him, All these things
will I give Thee, if Thou wilt fall down and worship me.
Matthew 28:16-20 Then The Eleven Disciples went away into Galilee, into a mountain where Iesus had appointed them.[17] And when they saw Him, they worshipped Him, but some doubted.[18] And Iesus came and spake unto them, saying,
All authority is given unto Me in Heaven and in Earth.
Revelation 11:14 The second woe is past; and, behold,
the third woe cometh quickly. ...Revelation 12:9-10 And
the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the Earth, and his angels were cast out with him. ...[12] Therefore rejoice, ye Heavens, and ye that dwell in them.
Woe to the inhabiters of the Earth and of the sea! for the devil is come down unto you, having great wrath, because he knoweth that he hath but a short time.
Revelation 17:12-17 And the ten horns which thou sawest are ten kings, which have received no kingdom as yet; but receive power as kings one hour with the beast. ...[16] And the ten horns which thou sawest upon the beast, these shall hate the harlot, and shall make her desolate and naked, and shall eat her flesh, and burn her with fire.[17]
For God hath put in their hearts to fulfil His will, and to agree, and give their kingdom unto the beast, until the words of God shall be fulfilled.
