How do we know grace through faith is true?

The truth of salvation through grace alone by faith is firmly established in Scripture. Ephesians 2:8-9 states that we are saved by grace through faith, and this not of ourselves; it is the gift of God. Galatians 2:16 asserts that a person is not justified by the works of the law but through faith in Jesus Christ. These passages show that grace lifts the burden of the law, providing believers the assurance that their salvation is grounded in Christ's perfect righteousness rather than their efforts. Salvation is thus anchored in God's grace, not in our works, making it a secure foundation.
