How do we know that knowledge of Christ is necessary for salvation?

The necessity of knowledge for salvation is emphasized in Scripture, particularly in Romans 10:14-17, which states that one cannot call on the name of the Lord unless they believe, and they cannot believe unless they have heard. This highlights the sequence of hearing the Gospel, gaining knowledge about Jesus, and then responding with faith. Additionally, Acts 9 illustrates this when Paul, despite his zealous knowledge as a Pharisee, needed a divine revelation to truly see Christ for who He is. Knowledge leads to understanding our need for salvation and the Savior Himself, whose identity is crucial for faith.
