Good and evil are not abstract ideas or human constructs—they are real, moral realities rooted in the very nature of God and the choices of His creation. The Bible reveals that all things were created good, yet through rebellion, evil entered the world as a corruption of that goodness. While God remains perfectly righteous and sovereign over all, evil continues to operate for a time, influencing the world and testing the hearts of men. This study explores the origin of evil, the role of Satan, the responsibility of each individual, and the ultimate truth that good will prevail when God brings final judgment and restores all things.
