How does God's purpose relate to salvation?

Scripture asserts that salvation is not a product of human will or effort but is according to God's sovereign purpose and grace. 2 Timothy 1:9 states that God saved us and called us not according to our works but according to His own purpose and grace given in Christ. This points to the truth that before the foundation of the world, God chose His people for salvation, as detailed in Ephesians 1:4-5. Understanding God's sovereign purpose offers believers assurance of their salvation, knowing it rests on God's unchanging will rather than their fluctuating faith or actions.
