Why is the concept of God's control over good and evil important for Christians?

The affirmation of God's sovereignty over both good and evil serves to deepen the believer's faith, particularly in times of suffering and uncertainty. By recognizing that God is not only aware of suffering but that He also has a purpose for it, Christians can endure trials with hope. For instance, when Joseph's brothers intended harm against him, he remarked, "You meant it for evil, but God meant it for good" (Genesis 50:20). This reflects the profound truth that God can bring about good through evil circumstances, ultimately working for His glory and the benefit of His elect. This doctrine cultivates a steadfast trust in God’s sovereignty and encourages believers to rely on His wisdom and goodness, even when they do not understand their circumstances.
