How do we know that only one truth exists in Christianity?

The idea that there is only one truth is rooted in the teachings of Scripture that declare Jesus as the exclusive way to the Father. John 14:6 records Jesus saying, 'I am the way, the truth, and the life; no one comes to the Father except through me.' This asserts a narrow path to salvation, highlighting that while the world may present many alternatives, the biblical perspective affirms there is one gospel and one Savior. As believers, understanding this exclusivity is essential because it guides the way we live and witness as we share the truth of Christ's redemptive work with others.
