What does the Bible say about God's purpose for salvation?

God's purpose for salvation is profoundly rooted in His eternal plan and covenant of grace. For example, God told Abraham in Genesis 15 that his descendants would be in bondage for 400 years, after which He would deliver them. This foreshadowed the redemption of God's elect, showcasing that God has a deliberate and sovereign purpose behind every historical event, including our salvation. Before the foundation of the world, God decided whom He would save and how, showing that His salvation is not random but intentional and purposeful.
