Lydia, a rich believer, invites the disciples to stay with her in her home and they accept. She is just one example of many benefactors that assist the apostles work, just as they assisted Jesus' work. To further the Good News, we need to avail ourselves of the gifts of all God's people, not just some.
Acts 16:11-15
We set sail from Troas and took a straight course to Samothrace, the following day to Neapolis, and from there to Philippi, which is a leading city of the district of Macedonia and a Roman colony. We remained in this city for some days. On the sabbath day we went outside the gate by the river, where we supposed there was a place of prayer; and we sat down and spoke to the women who had gathered there. A certain woman named Lydia, a worshipper of God, was listening to us; she was from the city of Thyatira and a dealer in purple cloth. The Lord opened her heart to listen eagerly to what was said by Paul. When she and her household were baptized, she urged us, saying, ‘If you have judged me to be faithful to the Lord, come and stay at my home.’ And she prevailed upon us.
