How do we know that Christ's atonement is limited?

Limited atonement teaches that Christ died specifically for His elect, not for everyone without exception. John 10:15 emphasizes this when Jesus states, 'I lay down my life for the sheep.' This indicates that His atoning sacrifice is effective for those declared as His people. Additionally, Matthew 1:21 affirms that He came to 'save His people from their sins,' indicating a specific group chosen by God rather than a universal application. Understanding this aspect of Christ's atonement deepens our appreciation of the particular and intentional nature of God's grace.
