How do we know that salvation is found only in Christ?

In Acts 4:12, it is declared that 'there is no other name under heaven given among men by which we must be saved,' affirming the uniqueness of Jesus Christ as the sole source of salvation. Throughout Scripture, we see that salvation is not a result of human effort or adherence to law, but through faith in Christ alone (Ephesians 2:8-9). The writings of the Apostle Paul also confirm this, as seen in Romans 3:22-24, where he elaborates on righteousness through faith in Jesus Christ for all who believe. This underscores the foundational Reformed doctrine that salvation is by grace alone through faith alone, in Christ alone.
