How do we know the apostles' message of salvation is true?

The validity of the apostles' message of salvation is affirmed through the continuity of the scriptures. Acts 16:31 records the command of Paul and Silas to believe in Christ for salvation. This message aligns with the prophetic scriptures that declare God's redemptive plan through Jesus, as noted in Romans 1:2-3, which speaks of the gospel promised by the prophets. Furthermore, the transforming effects in the lives of individuals, such as the conversion of the jailer and his family, serve as tangible evidence of the power of the gospel to deliver from sin and grant eternal life. Scripture emphasizes that Christ is the central figure of salvation, fulfilling the law and the prophets (Matthew 5:17), thus validating the apostles' proclamation.
