How do we know that God uses persecution for good?

God's sovereign plan often involves the use of persecution to fulfill His purposes, as illustrated in Acts 8. The persecution of Christians in Jerusalem following Stephen's death resulted in the scattering of believers who then preached the Word of God in various regions, notably in Samaria. This demonstrates God's ability to bring good out of suffering and His power to turn evil into opportunities for the advancement of His kingdom. The outpouring of joy in the cities where they preached (Acts 8:8) further underscores how God transforms trials into triumphs for His glory.
