2 Corinthians 11:28

‘Besides those things that are without (or ‘that I have left out’), there is that which presses on me daily, anxiety for all the churches.’

And there were other difficulties too, but he could not include them all. And as hard as all these troubles put together was the burden of care he bore for all the churches, which pressed on him daily. Always thinking of them, always praying for them, always wondering how he can encourage them, always trying to work out the best way that he can help them. ‘All the churches.’ That is, those that he and his companions have founded. (How are his opponents comparing now? Do they have many churches that they constantly bear a burden for?)
