How do we know the concept of God's sovereignty is true?

The concept of God's sovereignty is foundational in Reformed theology, emphasizing that God is in complete control over all circumstances and events. The scripture supports this doctrine, stating that the Lord killeth and maketh alive (1 Samuel 2:6) and that He raises up the poor out of the dust (1 Samuel 2:8). This demonstrates that nothing happens outside of His providential order. Hannah's prayer showcases the belief that God orchestrates both the riches and poverty of man, affirming that it's not based on human effort but according to God's mercy and purpose. Therefore, acknowledging God's sovereignty radically transforms our understanding of salvation, which is graciously given and not earned.
