How do we know salvation comes through faith in Jesus?

Scripture presents a clear message of salvation through faith in Jesus as central to the Christian doctrine. Romans 3:24 states that we are justified freely by His grace through the redemption that is in Christ Jesus. This emphasizes that our acceptance before God does not stem from any merit of our own but solely through faith in the redemptive work of Christ. The assurance of our salvation lies in God's sovereign grace, which is the foundation for our calling and the assurance of eternal life. Furthermore, Romans 5 declares that through Adam's disobedience many were made sinners, so through the obedience of Christ shall many be made righteous, reinforcing that faith in Jesus is the only path to justification and righteousness before God.
