Grace alone is vital for Christians as it emphasizes that salvation is a gift from God, unattainable by human effort, as stated in Ephesians 2:8-9.
The doctrine of grace alone is fundamental to the Christian faith because it underscores the belief that salvation is entirely a work of God. Ephesians 2:8-9 teaches us that 'by grace are you saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast.' This highlights that humans cannot earn or merit their salvation through works or personal righteousness. Instead, it is through God's unmerited favor that we are redeemed. The assurance of grace allows Christians to rest in the sufficiency of Christ's atonement while giving all glory to God for our salvation.
