How do we know the doctrine of grace alone is true?

The truth of grace alone is firmly established in scripture. Ephesians 2:8-9 indicates that our salvation comes through faith, which is itself a gift from God, underscoring that we cannot earn our way into salvation through any good works. Additionally, passages such as Colossians 1:5 and 2 Thessalonians 2:13 affirm that God has chose believers for salvation through His grace and the truth of the Gospel. This doctrine reflects the core of the Christian faith and aligns with the teachings of the Apostle Paul, who preached grace unapologetically.

The sovereign grace of God assures believers that their salvation is secure, not dependent on their changing circumstances or performances. This assurance is a cornerstone of Reformed theology, which emphasizes God's sovereignty over human destiny, underscoring the importance of faith rooted in grace for all aspects of salvation.
