Ephesians 3:4

Let a man so account of us, as of the ministers of Christ, and stewards of the mysteries of God.

Withal praying also for us, that God would open unto us a door of utterance, to speak the mystery of Christ, for which I am also in bonds:

But though I be rude in speech, yet not in knowledge; but we have been throughly made manifest among you in all things.

Howbeit we speak wisdom among them that are perfect: yet not the wisdom of this world, nor of the princes of this world, that come to nought: But we speak the wisdom of God in a mystery, even the hidden wisdom, which God ordained before the world unto our glory:

And without controversy great is the mystery of godliness: God was manifest in the flesh, justified in the Spirit, seen of angels, preached unto the Gentiles, believed on in the world, received up into glory.

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;

Having made known unto us the mystery of his will, according to his good pleasure which he hath purposed in himself:

This is a great mystery: but I speak concerning Christ and the church.

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,

And he said, Unto you it is given to know the mysteries of the kingdom of God: but to others in parables; that seeing they might not see, and hearing they might not understand.

And though I have the gift of prophecy, and understand all mysteries, and all knowledge; and though I have all faith, so that I could remove mountains, and have not charity, I am nothing.

Holding the mystery of the faith in a pure conscience.

And the angel said unto them, Fear not: for, behold, I bring you good tidings of great joy, which shall be to all people. For unto you is born this day in the city of David a Saviour, which is Christ the Lord.

He answered and said unto them, Because it is given unto you to know the mysteries of the kingdom of heaven, but to them it is not given.
