What roles do the Father, Son, and Holy Spirit play in salvation?

In the economy of salvation, each person of the Trinity plays a distinct yet unified role. The Father is the one who elects individuals unto salvation, as seen in the eternal covenant of grace. The Son, Jesus Christ, accomplishes redemption through His sacrificial death and resurrection, fulfilling the law and satisfying God's wrath. The Holy Spirit then works in the lives of the elect, regenerating them and enabling them to respond to the Gospel in faith. This trinitarian involvement ensures that salvation is entirely God's work from start to finish, underscoring the necessity for believers to attribute their faith and perseverance to divine grace.
