Most Galatians immediately rejected His message as told through Paul, not because Paul was ineffective, but because most Galatians were already wedded to the cult of Augustus which had already been established for almost a generation by the time of Paul's arrival.

The analogy is well chosen. The meme is also good.

BUT

Paul's real-time effectiveness was also shored up over time up by his letters back to the towns he last visited.

Upshot, keep sending letters.
