what does the bible say?
God knows ahead of time who will rule a given nation, and those rulers exist under His sovereign control (Romans 13:1–7). Regardless of whether the ruler is evil or good, God has control of the person in charge of every nation. God can turn the heart of a king wherever He will (Proverbs 21:1).
The Bible has many examples of evil rulers, yet God ultimately controlled their reigns and the outcomes. Pharaoh sought to keep the Israelites as slaves, even after God sent Moses to tell him to let them go. Despite Pharaoh's evil oppression, God's will prevailed. The book of Judges offers many examples of times when God's people lived under oppression, cried out for help, and then were given new leadership raised up by God. In the New Testament, the early church encountered much opposition from governing leaders (Acts 8). But the persecution helped spread the gospel (Acts 8:4).
