How does Jesus ensure our eternal security?

The eternal security of believers is rooted in the complete and final nature of Christ's work on the cross. John 10:28-29 assures us that no one can snatch the sheep from the hand of Christ, emphasizing that once we are in His care, we are secure. This security is not based on our works but on Christ’s righteousness imputed to us. Since He bore the full measure of God's wrath on our behalf, as stated in Isaiah 53:5, we can rest assured that our salvation is secure. Furthermore, Romans 8:38-39 concludes that nothing can separate us from the love of God in Christ, reinforcing the assurance that our eternal standing is secure in Him.
