What does the Bible say about the origin of evil?

The Bible does not provide a detailed exposition on the origin of evil as a primary focus. Instead, it emphasizes God's loving action in providing salvation through Jesus Christ, whose sacrifice addresses the presence of sin in the world. As Mr. Spurgeon reflects, our focus should not be on how evil entered but on recognizing that through Christ, evil is dealt with and ultimately vanquished. This perspective aligns well with the Reformed understanding of the sovereignty of God over all creation, including the matter of evil.
