9 He made known to us the mystery of His will, according to His kind intention which He purposed in Him
3 that by revelation there was made known to me the mystery, as I wrote before in brief.
5 which in other generations was not made known to the sons of men, as it has now been revealed to His holy apostles and prophets in the Spirit;
10 so that the manifold wisdom of God might now be made known through the church to the rulers and the authorities in the heavenly places.
19 and pray on my behalf, that utterance may be given to me in the opening of my mouth, to make known with boldness the mystery of the gospel,
21 But that you also may know about my circumstances , how I am doing, Tychicus, the beloved brother and faithful minister in the Lord , will make everything known to you.
