How do we know the salvation revealed in Scripture is true?

The assurance of salvation comes through the recognition that Jesus Christ fulfills all righteousness and the law's demands on behalf of His people. Romans 10:4 states, 'For Christ is the end of the law for righteousness to everyone that believes.' This encapsulates the essence of the gospel, wherein Christ becomes the perfect substitute for sinners, redeeming them from the curse of the law through His sacrificial death. This truth is not merely a doctrine but a reality experienced by those who are united with Him in faith. The promises of Scripture provide a foundation for believers to trust in their salvation, reinforcing that it is through faith, a gift from God, that one receives eternal life.
