"During this time some prophets traveled from Jerusalem to Antioch. One of them named Agabus stood up and in one of the meetings and predicted by the Spirit that a great famine was coming upon the entire Roman world. (This was fulfilled during the reign of Claudius.) So the believers in Antioch decided to send relief to the brothers and sisters in Judea, everyone giving as much as they could. This they did, entrusting their gifts to Barnabas and Saul to take to the elders of the church in Jerusalem."
God knows our needs, long before we discover them. And He provides, many times in unexpected ways. We can make all the plans we want, based off our resources, but God uses resources we didn't think of or know about.
