How do we know that salvation is possible through Christ?

Salvation through Christ is grounded in Scripture, particularly Romans 3:24 and Romans 8:1. These verses underline that believers are justified freely by God's grace through redemption in Christ Jesus and that there is no condemnation for those who are in Him. Christ, as the second Adam, fulfilled the law and bore the wrath of God on behalf of His people, thus ensuring that salvation is not based on human effort but solely on His work. This divine substitution confirms the certainty of salvation only for those who are united by faith with Christ.
