What does the Bible teach about the sovereignty of God in salvation?

Sovereign grace theology posits that God is the ultimate authority in salvation, choosing to save whom He wills. This is evidenced in Scripture where God's sovereign choice is clear, notably in Ephesians 1:4-5, which states that He chose us in Christ before the foundation of the world. The theme of divine sovereignty is consistent throughout both the Old and New Testaments, portraying God’s active role in orchestrating salvation history. Hosea 5 serves as a reminder that Israel, despite their sin, received God's mercy—not because they deserved it, but because of God's sovereign will and everlasting love. Romans 9 emphasizes this, stating that God shows mercy on whom He wills, underscoring the grace given freely without human merit.
