Remember the Poor (Jews)
Gal 2:10 All they asked was that we should continue to remember the poor, the very thing I was eager to do.
The last time Paul and Barnabus visited Jerusalem was in Acts 11 where it is written, "for a whole year Barnabas and Saul met with the church and taught great numbers of people. The disciples were called Christians first at Antioch. During this time some prophets came down from Jerusalem to Antioch. One of them, named Agabus, stood up and through the Spirit predicted that a severe famine would spread over the entire Roman world. (This happened during the reign of Claudius.) The disciples, each according to his ability, decided to provide help for the brothers living in Judea. This they did, sending their gift to the elders by Barnabas and Saul." Acts 11:26-30
If the famine was to be over the whole Roman world, then why direct their gifts to the brothers in Judea? First of all Judea was almost entirely dependent upon rainfall for water. So the land was particularly prone to suffer during famines. And Jewish Christians had it especially difficult, being persecuted by unbelieving Jews. Thus Jewish Christians were generally among the poorest. And having become accustomed to receiving financial support, I have the impression, I don't think that James, Peter and John had poor Gentile Christians in mind by this instruction, but rather they were simply trying to secure more contributions for their own church. For while they had reluctance in receiving Gentile Christians, they had no reluctance receiving their money.
And Paul was eager to raise financial support for their church, as were the Gentiles Christians. Paul writes in Rom 15:25-27 "But now I am going to Jerusalem to minister to the saints. For it pleased those from Macedonia and Achaia to make a certain contribution for the poor among the saints who are in Jerusalem. It pleased them indeed, and they are their debtors. For if the Gentiles have been partakers of their spiritual things, their duty is also to minister to them in material things."
The generosity of the Gentiles no doubt became another element in helping Jewish Christians, like James, Peter and John, to overcome their prejudice and reluctance to fellowship with them.
