How can we find reassurance in Christ's finished work?

The reassurance found in Christ's finished work stems from the reality that He accomplished everything necessary for salvation. The sermon emphasizes that His declaration, 'It is finished,' signifies the completion of the work of redemption (John 19:30). When Christians recognize that their sins have been paid for in full and that Christ's resurrection confirms their justification, it brings peace and assurance. This understanding frees us from anxiety and allows us to proclaim 'fear not,' knowing that our standing before God is secure in Christ (Romans 5:1).
