The understanding of the Trinity and how God saves us is critical. God the Father predestines us, The Son redeems us in His atonement, and the Holy Spirit regenerates us and causes us to persevere through sanctification. All aspects of the plan of salvation are controlled by God the Father, Son and Holy Spirit.
The Father Predestines
He predestines us in that He created us and governs all our actions through His providence. He works through the means of Baptism, the Lord’s Supper, and the preaching of the Word to bring us to Christ.
The Son Redeems
He redeems His people by dying for their sins and raising from the dead. Christ’s death on the cross forgave the sins of His people for all time; past, present and future. Christ’s resurrection causes His people to spiritually be born again and regenerated by His Spirit.
The Holy Spirit Seals
He applies the redemption of God’s people whom were predestined before before creation. The Holy Spirit regenerates God’s people and grants them repentance and faith. The repentance and faith results in their justification and thus are adopted children of God. The Holy Spirit sanctifies God’s people and causes them to do good works as evidence of their faith. These are the saving graces that God gives us for our salvation. God’s people are kept in the faith by the work and power of the Holy Spirit.
Therefore: Salvation is from God alone
For by grace you have been saved through faith; and that not of yourselves, it is the gift of God; not as a result of works, that no one should boast. (Eph 2:8-9 NAS)
