How do we know that Christ is a successful Savior?

The story of Bartimaeus in Mark 10 illustrates Christ's successful redemptive work. When Bartimaeus calls out to Jesus, he demonstrates faith in the only one who can provide what he cannot achieve himself: sight and salvation. Jesus responds to this faith, highlighting that those who come to Him in their need will never be turned away empty. This reflects the assurance that all whom Christ came to save will indeed be saved. We see this affirmation in Jesus' words, 'Thy faith hath made thee whole,' indicating that faith in Christ leads to both physical and spiritual renewal.
