How do we know salvation through Jesus Christ is true?

The validity of salvation through Jesus Christ is firmly anchored in biblical revelation. The Apostle Paul, in Romans 1:16, asserts that the Gospel is the power of God for salvation to all who believe, validating its truth through the witness of Scripture and the active work of the Holy Spirit in believers' lives. Moreover, Jesus' resurrection serves as the ultimate confirmation of His redemptive work, as the defeat of sin and death assures believers of their own salvation. Ultimately, the ongoing transformation in believers' lives affirms the truth of salvation, making them new creations (2 Corinthians 5:17).
