What does it mean that salvation is a work of God?

When we say that salvation is a work of God, we affirm that every aspect of salvation—from election, regeneration, justification, to sanctification—is God's doing. Ephesians 1:7-12 articulates this by stating that 'in whom we have redemption through his blood,' highlighting that Christ's sacrificial work is the foundation upon which our salvation rests. The involvement of the Triune God—Father, Son, and Holy Spirit—is essential to understanding that salvation is not a result of human action or decision, but rather a divine initiative that ensures the security of the believer. This reveals the depth of God's love and His desire for a relationship with us, as He performs the necessary work in our hearts, leading us to true repentance and faith.
