Here’s the text for today in the NET translation.
15:25 But now I go to Jerusalem to minister to the saints. 15:26 For Macedonia and Achaia are pleased to make some contribution for the poor among the saints in Jerusalem. 15:27 For they were pleased to do this, and indeed they are indebted to the Jerusalem saints. For if the Gentiles have shared in their spiritual things, they are obligated also to minister to them in material things. 15:28 Therefore after I have completed this and have safely delivered this bounty to them, I will set out for Spain by way of you, 15:29 and I know that when I come to you I will come in the fullness of Christ’s blessing.
In this account, Paul talks about the generosity of the Macedonian and Achaian believers towards the poor believers in Jerusalem. Twice he says they were “pleased” to do so. This shows their attitude. It was not a grudgery, but a delight for them to send funds with Paul.
I also found their motivation interesting. In this case they weren’t giving out of compassion or pity. They were repaying the Jerusalemites for their previous generosity to them. They recognized that they were indebted to them spiritually and so now they were happy to repay them materially. It was a delight for them to have a reciprocal “we need each other” type of relationship with their fellow-believers.
So now for my application. To whom am I indebted (spiritually or otherwise) and consequently to whom should it be my delight to bless in some way?
