What does the Bible say about religious freedom?

In Acts 18:12-16, we find Paul protected by Gallio from the accusations of the Jews, highlighting that the magistrate's office is not to judge in matters of religious beliefs. This scene exemplifies the principle that believers should enjoy freedom from persecution in their worship and expression of faith. It is a reflection of God's divine providence allowing Christians to practice their faith without undue interference from civil authorities.

Moreover, the passage showcases that while Gallio, an enlightened magistrate, refused to examine the case based on religious grounds, it reveals a deeper truth about liberty of conscience, which is crucial for a thriving Christian life. The early Christians experienced various forms of persecution, yet the overarching theme in Scripture is God's sovereignty over human affairs, ensuring that His people are ultimately safe under His providential care, regardless of the rulers imposed over them.
