How do we know that God's sovereignty includes salvation?

God's sovereignty over salvation is prominently displayed throughout the scriptures. In Ephesians 1:4-5, we read about God's predestination of believers before the foundation of the world, emphasizing that our salvation is part of His divine plan. Furthermore, Romans 9:16 clarifies that 'it is not of him that willeth, nor of him that runneth, but of God that sheweth mercy.' This illustrates that it is ultimately God's will and mercy that determine salvation, not human effort or desire. Recognizing God's complete authority in the process of salvation gives believers assurance of their eternal security, knowing they are chosen and kept by His unmatched grace.
