Why do Christians believe in the sovereignty of God?

The belief in the sovereignty of God is rooted in the understanding that He is the almighty Creator and sustainer of all things. Acts 4:24 states that God made the heavens and the earth, underscoring His supreme authority over creation. Throughout the Bible, God is portrayed as one who directs the course of events according to His purpose, as in Romans 8:28, where all things work together for good to those who love Him. This sovereignty assures believers that nothing happens outside of His will, leading to confidence in His plans for salvation and providence in their lives.
