The salvation of the Lord is true because it is grounded in the atoning work of Jesus Christ, who fulfilled Scripture.
The message of salvation is rooted in Isaiah 40, which calls to prepare the way of the Lord. This preparation points to the coming of Jesus Christ, who became a substitute for His people, enduring the wrath of God as depicted in Isaiah 53. He is described as a 'tender plant' and 'a root out of dry ground,' showing His role in taking upon Himself the judgment due to humanity. Therefore, the truth of salvation is confirmed through Christ's life, death, and resurrection, fulfilling God's promise to redeem His people and emphasizing that those who are in Christ have their iniquities pardoned (Isaiah 40:2).
