Acts 16:14-15

14A woman named Lydia, from the city of Thyatira, a dealer in purple fabrics who was [already] a worshiper of God, listened to us; and the Lord opened her heart to pay attention and to respond to the things said by Paul.

15And when she was baptized, along with her household, she pleaded with us, saying, “If you have judged me and decided that I am faithful to the Lord [a true believer], come to my house and stay.” And she persuaded us.
