That is exactly as I understand it...
Then I have no doubt you understand these verses:
"Having made known unto us the mystery of his will, according to his good pleasure which he hath purposed in himself:..."(Eph. 1:9); "That the God of our Lord Jesus Christ, the Father of glory, may give unto you the spirit of wisdom and revelation in the knowledge of Him.."(Eph. 1:17-18); "For this cause we also, since the day we heard it, do not cease to pray for you, and to desire that ye might be filled with the knowledge of his will in all wisdom and spiritual understanding" (Col. 1:9); "Even the mystery which hath been hid from ages and from generations, BUT NOW is made manifest to his saints: TO whom God would make known what is the riches of the glory of this mystery among the Gentiles: which is Christ in you, the hope of glory:" (Col. 1:26,27); "That their hearts might be comforted, being knit together in love, and unto all riches of the full assurance of understanding, to the acknowledgement of the mystery of God, and of the Father, and of Christ:" (Col. 2:2).
