How do we know salvation through the gospel is true?

The Apostle Paul states in Romans 1:16, 'I am not ashamed of the gospel, for it is the power of God for salvation to everyone who believes.' The truth of salvation through the gospel is affirmed in its power to transform lives, as well as through its consistency with God’s holiness and justice. Throughout scripture, God reveals Himself as a just God who cannot tolerate sin yet desires to save sinners. The gospel encapsulates this by presenting Jesus, who bore the wrath of God against sin, thus enabling believers to receive grace and reconciliation. The historical accounts of Jesus' life, death, and resurrection serve as the ultimate proof that the gospel brings genuine salvation and fulfills God’s promises.
