What are the roles of the Father, Son, and Holy Spirit in salvation?

In the Trinity, each person has a unique role in the salvation process. The Father is the one who elects and predestines a people for Himself, as seen in Ephesians 1:4-5. The Son, Jesus Christ, accomplished the work of redemption through His life, death, and resurrection, which is the means by which the elect are saved. Finally, the Holy Spirit is the one who regenerates the hearts of believers, effectively applying the work of Christ to them, as stated in John 3:3 where Jesus says, 'You must be born again.' It's vital to understand that while each person has distinct roles, they are one in essence, working harmoniously for the salvation of God's chosen people.
