Check out this entry from Luke’s journal (He is writing about how God work in and through an ordinary woman named Lydia).
The Lord opened her heart to respond to Paul's message. When she and the members of her household were baptized, she invited us to her home. "If you consider me a believer in the Lord," she said, "come and stay at my house." And she persuaded us. Acts 16:14-15
What impresses me about Lydia is how she immediately connected being a believer with acts of service. As soon as God opened her heart, she opened her home.
I love the practical faith of Lydia. As far as we know she never led a Bible study, went on a mission trip, or sang in the choir. She didn't go on the road with Paul, or debate about theology in the marketplace. All she did was open her heart to God and open her home to God’s family. All she did was put her faith into action. All she did was have the audacity to believe that God would show up where she lived.
Turns out, the church of Philippi was born in Lydia’s house. And one of the best loved books in the Bible, Philippians, was written. All because an ordinary woman had the audacity to believe that God would show up where she lived.
