2 Corinthians 4
(3) But if our gospel be hid, it is hid to them that are lost:
(4) In whom the god of this world hath blinded the minds of them which believe not, lest the light of the glorious gospel of Christ, who is the image of God, should shine unto them.
(5) For we preach not ourselves, but Christ Jesus the Lord; and ourselves your servants for Jesus' sake.
Revelation 12:
(7) And there was war in heaven: Michael and his angels fought against the dragon; and the dragon fought and his angels,
(8) And prevailed not; neither was their place found any more in heaven.
(9) 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.
The greatest weapon of a stealth fighter, is to get people to believe he dosen't exist. May the Lord of all Grace open your eyes.
