How do we know salvation through grace is true?

The truth of salvation by grace is firmly rooted in Scripture, especially in the writings of the Apostle Paul. In Ephesians 2:8-9, Paul writes that salvation is by grace through faith, not from works, lest anyone should boast. This underscores that salvation is not the result of human effort, but a gift from God. The consistent biblical theme of grace is that it is God’s unmerited favor freely given to sinners through the person and work of Jesus Christ, making it foundational to Reformed theology.
