Romans 11:25 For I would not, brethren, that ye sould be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is hapened to Israel, until the fulness of the Gentiles be come in.
Romans 16:25 Now to Him That is of power to stablish you according to my gospel, and the preaching of Jesus Christ, according to the revelation of the mystery, which was kept secret since the world began, (26) But now is made manifest, and by the scriptures of the prophets, according to the commandment of the everlasting god, made known to all nations for the obedience of faith:
1 Corinthians 2:7 But we speak the wisdom of God in a mystery, even the hidden wisdom, which God ordained before the world unto our glory: (8) Which none of the princes of this world knew: for had they known it, they would not have crucified the Lord of glory. Who crucified the Lord? Who are the princes of this world? Who rules this world?
Matthew 9:34 But the Pharisees said, "He casteth out devils through the prince of the devils."
John 12:31 Now is the judgment of this world: now shall the prince of this world be cast out.
The devil rules the world (now) but he will be crushed. It appears there are mysteries that are from the beginning (the foundation of this age and from the Garden of Eden) but those mysteries are found in scripture and are "made manifest by the prophets". They are there. God tells us they are there.
Ephesians 6:19 And for me, that utterance may be given unto me, that I may open my mouth boldly, to make known the mystery of the gospel.
We are supposed to know these mysteries that Paul taught. He taught about the three ages of earth and about the ancestry of Cain.
