God [in His eternal plan] chose to make known to them how great for the Gentiles are the riches of the glory of this mystery, which is Christ in and among you, the hope and guarantee of [realizing the] glory.
God ·decided [chose; willed] to let his people know this rich and glorious ·secret [mystery; 1:26] which he has for ·all people [the nations/Gentiles]. This ·secret [mystery] is ·that Christ lives in you. He is our only hope for glory [L Christ in you, the hope of glory].
God's plan is to make known his secret to his people, this rich and glorious secret which he has for all peoples. And the secret is that Christ is in you, which means that you will share in the glory of God.
I myself have been made a minister of this same Gospel, and though it is true at this moment that I am suffering on behalf of you who have heard the Gospel, yet I am far from sorry about it. Indeed, I am glad, because it gives me a chance to complete in my own sufferings something of the untold pains for which Christ suffers on behalf of his body, the Church. For I am a minister of the Church by divine commission, a commission granted to me for your benefit and for a special purpose: that I might fully declare God’s word—that sacred mystery which up to now has been hidden in every age and every generation, but which is now as clear as daylight to those who love God. They are those to whom God has planned to give a vision of the full wonder and splendour of his secret plan for the sons of men. And the secret is simply this: Christ in you! Yes, Christ in you bringing with him the hope of all glorious things to come.
He has kept this secret for centuries and generations past, but now at last it has pleased him to tell it to those who love him and live for him, and the riches and glory of his plan are for you Gentiles, too. And this is the secret: Christ in your hearts is your only hope of glory.
This mystery has been kept in the dark for a long time, but now it’s out in the open. God wanted everyone, not just Jews, to know this rich and glorious secret inside and out, regardless of their background, regardless of their religious standing. The mystery in a nutshell is just this: Christ is in you, so therefore you can look forward to sharing in God’s glory. It’s that simple. That is the substance of our Message. We preach Christ, warning people not to add to the Message. We teach in a spirit of profound common sense so that we can bring each person to maturity. To be mature is to be basic. Christ! No more, no less. That’s what I’m working so hard at day after day, year after year, doing my best with the energy God so generously gives me.
