How does Jesus justify His people?

Jesus Christ justifies His people by taking the punishment for their sins and fulfilling all righteousness on their behalf. As stated in Isaiah 53:5, He was wounded for our transgressions, and through His death, He reconciles His elect to God by satisfying divine justice. This act of justification is crucial because it removes the legal barriers between God and His people while also imparting Christ’s perfect righteousness to them, ensuring their acceptance before God. His justification is not merely a declaration but provides the foundation for their relationship with God, ensuring their security and sanctification.
