The Trinity of salvation is God as Father, Son and Holy Spirit. The triune God is our salvation. One eternal God is experienced in our salvation. Consider how our salvation is the work of the Holy Trinity.
Salvation is from the Father, through the Son and by the Holy Spirit. You come to know God as your Father, through faith in God the Son, our Lord Jesus Christ. The only way to God the Father is through God the Son (John 14:1-6). Salvation is applied to you by God the Holy Spirit. The Godhead is revealed to you in salvation.
God the Holy Spirit enables you to come by faith to God the Son. "No one can say Jesus is Lord except by the Holy Spirit" (1 Corinthians 12:3). God the Holy Spirit leads you to believe the gospel. You believe Christ died for your sins. You believe Christ is risen from the dead. You believe and confess Jesus is Lord.
God the Holy Spirit gives the assurance of your salvation, as you confess Jesus is Lord. "The Spirit Himself bears witness with our spirit that we are children of God" (Romans 8:16). This is your assurance: "If you confess with your mouth the Lord Jesus and believe in your heart that God raised Him from the dead, you will be saved" (Romans 10:9).
