What does the Bible say about Lydia's conversion?

In Acts 16:14, we see Lydia, a seller of purple from Thyatira, as an example of how conversion is a work of God. The scripture states that the Lord opened her heart, enabling her to attend to the truths spoken by Paul. This emphasizes that belief is not merely a result of human effort but is initiated by God's sovereign grace. The passage illustrates that regardless of how compelling an argument might be, it is ultimately the Spirit of God who must convict and change the hearts of individuals.
