How do we know that Jesus is the only true Savior?

In Job 33:23-24, Elihu represents a type of Christ, indicated by the term 'one among a thousand.' Elihu's name suggests that he is a representation of God with us, similar to Jesus, referred to as Emmanuel. Moreover, in Isaiah 7:14, we learn about Immanuel, further affirming that Jesus is the one and only Savior, uniquely qualified by His divine nature. The Scriptures teach that no one else can bring salvation—Acts 4:12 declares that there is no other name under heaven given among men by which we must be saved. Thus, understanding the exclusivity of Christ in salvation is crucial for the believer.
