What does the Bible say about God's purpose and grace?

God's purpose and grace are central themes in Scripture, emphasizing that salvation is not based on our works but solely on God's sovereign will. According to 2 Timothy 1:9, Paul states that God has saved us and called us with a holy calling according to His own purpose and grace, which was given us in Christ Jesus before the world began. This underscores the Reformed understanding of sovereign grace, affirming that our salvation is entirely dependent on God's sovereign choice rather than human effort.
