Ephesians 3:1-4

1 For this cause I, Paul, am the prisoner of Christ Jesus on behalf of you Gentiles,  2 if it is so that you have heard of the administration of that grace of God which was given me toward you;  3 how that by revelation the mystery was made known to me, as I wrote before in few words,  4 by which, when you read, you can perceive my understanding in the mystery of Christ;
