Why is it significant that salvation is a gift from God?

Salvation being a gift from God, as highlighted in Ephesians 2:8-9, underscores the foundational principle of grace in Reformed theology. If salvation were something we could earn through good works or adherence to moral standards, it would eliminate the need for grace and diminish the glory of God's redemptive plan. This gift assures believers that their standing before God does not depend on their performance but on Christ's perfect righteousness. It encourages humility and gratitude, as we recognize that our salvation is entirely an act of God's unmerited favor rather than a result of our efforts.
