13 And on the Sabbath day we went out of the city to the riverside, where prayer was customarily made; and we sat down and spoke to the women who met there. 14 Now a certain woman named Lydia heard us. She was a seller of purple from the city of Thyatira, who worshiped God. The Lord opened her heart to heed the things spoken by Paul. 15 And when she and her household were baptized, she begged us, saying, “If you have judged me to be faithful to the Lord, come to my house and stay.” So she persuaded us. (Acts 16:13–15, NKJV)
Paul and his companions looked for an opportunity to teach the gospel, and a group of women were found by the riverside. Among them was Lydia, whose heart the Lord opened “to heed the things spoken by Paul.” How and why did the Lord open Lydia’s heart? Does He still open hearts? First, Lydia was not shown preferential treatment over the other women. God opened her heart the way He does today, by the power of the gospel she heard. God’s saving word addresses the heart, convicting and converting the lost (John 16:8-13; Romans 1:16). Lydia’s heart was opened “to heed” the things Paul said (to give close attention to and respond). The gospel prompted her to answer God’s call to believe and be baptized to be saved (Mark 16:15-16). Her actions were deemed “faithful to the Lord” inasmuch as Paul and his companions lodged at her house. Lydia chose to heed the gospel and by doing so, she was faithful to the Lord.
