How do we know that Jesus is sovereign over salvation?

The sovereignty of Christ over salvation is foundational to Reformed theology. Jesus explicitly states that He came to save His people from their sins (Matthew 1:21), demonstrating that His redemptive work is directed towards His elect. Furthermore, in John 6:37, He assures us that 'all that the Father giveth me shall come to me,' reinforcing the belief that salvation is initiated and completed by Christ alone. This sovereignty grants believers security, as they are assured that nothing can separate them from His love (Romans 8:38-39).
