What does the Bible say about evil and God's purpose?

The Scriptures indicate that evil and sin are not outside of God's control; rather, they play a role in His divine plan. Psalm 76:10 specifically states that the wrath of man shall praise God. This suggests that human fury, stemming from our fallen nature, is still used by God to fulfill His purposes. In the grand narrative of redemption, evil must exist, so that God's justice, grace, and holiness might be manifest, especially through the sacrificial death of Christ, who bore our sins and secured true glory for God.

Moreover, it is vital to understand that the existence of evil provides the backdrop against which God's mercy and justice shine the brightest. Without evil, the depth of God's grace—the means by which He removes our sins—would not be fully displayed. The presence of sin heightens our understanding of salvation, demonstrating God's sovereign ability to turn even the worst intentions toward a glorious end.
