What does the Bible say about God's testing of believers?

Psalm 66:10-12 clearly states that God proves and tests His people much like silver is refined in fire. This testing is essential for believers as it confirms the authenticity of their faith. Throughout Scripture, such as the experiences of Shadrach, Meshach, and Abednego, we see that God's people are not exempt from trials. Rather, these afflictions are instrumental in preparing them for greater spiritual wealth and understanding. Testings are not merely punitive; they reveal the reality of one’s relationship with God and His faithfulness to deliver His followers.
