The Opening of Lydia’s Heart (Acts 16:14)

Calvinists frequently cite Lydia’s conversion in Acts 16:14 as evidence that God must first regenerate someone before he can respond to the gospel. But is this passage actually describing regeneration, or simply God helping Lydia understand and embrace the message about Christ?

To start with, Lydia was already a worshipper of God prior to her heart being opened. Consider the context of the passage:

“And on the Sabbath day we [Paul, Timothy, and Silas] 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. 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” (Acts 16:13-14).

Notice that the text does not say God gave Lydia a new heart, regenerated her, or made her spiritually alive. Rather, it says God opened her heart “to heed the things spoken by Paul.” The opening specifically concerns her response to Paul’s message about Jesus.

Cornelius

Cornelius provides another example of a God-fearing person whose understanding was incomplete prior to hearing the gospel. The book of Acts describes the Roman Centurian Cornelius—who was neither a Jew nor a Christian yet—as “a devout man and one who feared God with all his household, who gave alms generously to the people, and prayed to God always” (Acts 10:1-2).

The passage goes on to say that Cornelius’ prayers were heard (Acts 10:31). Keep in mind, God does not hear the prayers of the unrighteous (John 9:31, James 5:16).

Peter then said about Cornelius and others like him: “In every nation whoever fears Him [God] and works righteousness is accepted by Him” (Acts 10:35).

Although Cornelius still needed to hear the gospel and believe in Christ, Acts portrays him as a man who genuinely feared God and whose prayers and alms were accepted by God, even prior to hearing the gospel.

John the Baptist

Even faithful servants of God sometimes struggled to fully understand Jesus’ mission and identity because he did not meet the common Jewish expectations of Messiah. After his imprisonment, John the Baptist sent his disciples to ask Jesus:

“Are You the Coming One, or do we look for another?” (Matt. 11:3).

And Jesus said: “Go and tell John the things which you hear and see: The blind see and the lame walk; the lepers are cleansed and the deaf hear; the dead are raised up and the poor have the gospel preached to them. And blessed is he who is not offended because of Me” (Matt. 11:4-6).

Like Lydia and Cornelius, John the Baptist demonstrates that even God’s people sometimes needed further revelation and clarification concerning Jesus’ identity and mission. In John’s case, it was because Jesus did not meet the common Jewish expectations of Messiah. Most Jews expected Messiah to overthrow Rome politically, but Jesus came primarily to deliver people from sin.

Conclusion

Because of their prior choices to fear God, these people (Lydia, Cornelius, John the Baptist) were already genuine seekers and worshipers of God before receiving fuller revelation concerning Christ.

Keep in mind, I’m not saying there is salvation outside of Christ. There isn’t. Nevertheless, one does not need a perfected knowledge of God/Christ for Jesus to save him. The Old Testament saints are clear examples of this principle.

So Acts 16 presents Lydia not as a spiritually dead rebel incapable of responding to God, but as a worshiper of God whose heart was illuminated so she could recognize Jesus as the promised Messiah.
