Why is salvation all of grace important?

The doctrine of salvation by grace alone is central to Reformed theology, emphasizing that human merit plays no role in our salvation. Ephesians 2:8-9 clearly states, 'For by grace you have been saved through faith, and this is not your own doing; it is the gift of God, not a result of works, so that no one may boast.' This is critical because it establishes that salvation is entirely initiated and accomplished by God's grace through Christ's work, leaving no room for human pride or self-righteousness. Furthermore, this assurance aligns with 2 Corinthians 1:20 which declares, 'For all the promises of God find their Yes in him.' Every promise of salvation is fulfilled solely in Christ, reaffirming the glorious truth that we are saved by grace, through faith, and not by works.
