How does God use sin for His purposes?

While it may seem perplexing, God's sovereignty encompasses even the existence of sin. James reminds us that God's overarching purpose is to bring good out of evil (James 1:13). For instance, through the cross, the greatest evil was carried out by unjust men, yet it resulted in the ultimate good—the redemption of God's elect. God's foreknowledge ensured that these events would unfold to demonstrate His love, grace, and justice. Sin serves to illuminate God's attributes, making His grace more precious and His justice more necessary in the grand narrative of redemption.
