How is Christ related to the concept of federal headship?

Federal headship is a significant doctrine that illustrates how Christ represents His people before God. As the second Adam, Christ fulfills all the requirements of the law on behalf of those whom the Father has chosen to save. His obedience is imputed to them, meaning that believers are counted as righteous because of His righteous acts. This ties back to the principle found in Romans 5, where Paul contrasts the disobedience of Adam with the obedience of Christ. In this framework, when Christ acts, He does so not only for Himself but vicariously for all those who believe in Him, achieving their redemption and ensuring their acceptance in the sight of God. This understanding of federal headship assures believers that their salvation is secure, rooted in the success of their representative, Christ.
