Note:there is a central distinction between Paul labouring and God working through him.
A. 26 Even the mystery which hath been hid from ages and from generations, but now is made manifest to his saints:
B. 27 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: 28 Whom we preach, warning every man,
and teaching every man in all wisdom; that we may present every man perfect in Christ Jesus:
C. 29 Whereunto I also labour,
C’. striving according to his working, which worketh in me mightily.
B’. 2:1 For I would that ye knew what great conflict I have for you, and for them at Laodicea, and for as many as have not seen my face in the flesh; 2 That their hearts might be comforted, being knit to gether in love, and unto all riches of the full assurance of understand ing, to the acknowledgement
A’. of the mystery of God, and of the Father, and of Christ; 3 In whom are hid all the treasures of wisdom and knowledge.
