There is a new gospel, a fresh gospel, that is preached to every person, in every circumstance, and that gospel is going to always be slightly different from the gospel preached to the next guy. That is the strength of the gospel, not its weakness: that it can be all things to all men.
Paul was not saying something astonishing or scandalous when he says he is all things to all men: he was only saying of himself (since he was the servant of that gospel) what is true of the gospel itself, fitting itself into the ears of each one, for ‘faith comes by hearing, and hearing by the Word of God.’
Isn't that what is so good about the good news? That Christ who is Himself one person of the Divine and Holy Triad, sheds the might of His divinity, coming down to our level, to live among us, to speak our language, not just to feel our pain and endure the temptations we suffer.
If He must die on the Cross for our salvation, that cannot be conveyed to us, placed within our reach, without it being sized and fitted to the broken hearts of each of us. Yes, the Man of Sorrows, but also, the God of Joys. The latter doesn’t balance the former; it engulfs it like the sea engulfs a pebble, leaving no trace.
Hence, the gospel, always new, always fresh, containing all, supporting all, adapted to all, welcoming all, transforming all, but one by one, even as one by one we each receive the call, and one by one are seated at our places in the banquet of the Divine Nature, the wedding feast of the Lamb.
