What does the Bible say about God's sovereignty in choosing His people?

Scripture clearly states that God's sovereignty extends to His choosing of those who will be saved. Ephesians 1:4-5 affirms that God chose us in Christ before the foundation of the world, indicating His will and initiative in salvation. This choice is not based on any foreseen merit or decision on our part, as God operates outside of time and His decisions are rooted in His divine counsel. Additionally, Numbers 12 reflects this sovereignty as God personally addresses Miriam and Aaron's complaints, highlighting that His plans will not be thwarted by human opinion. God is sovereign not just in creation but also in redemption, calling whom He wills to salvation.
