What does the Bible say about God's sovereignty and election?

Scripture affirms God's sovereignty in choosing His people for salvation. Ephesians 1:4-5 states that God chose us in Christ before the foundation of the world, indicating predestination based on His purpose and not our merit. This is echoed in Isaiah 43:1-20, where God declares His chosen people as precious and claims them as His own. The essence of God's love and election rests in His grace, which He gives freely to those He has chosen, highlighting His sovereignty in the salvation process.
