Ephesians 3:3-5

Amplified Bible, Classic Edition

³ [And] that the mystery (secret) was made known to me and I was allowed to comprehend it by direct revelation, as I already briefly wrote you.

⁴ When you read this you can understand my insight into the mystery of Christ.

⁵ [This mystery] was never disclosed to human beings in past generations as it has now been revealed to His holy apostles (consecrated messengers) and prophets by the [Holy] Spirit.
