Why is it essential to believe in Jesus as the Son of God?

The belief in Jesus Christ as the Son of God distinguishes true faith from mere acknowledgment of facts. In John 9, when the blind man comes to understand who Jesus is, his belief leads him to worship. This belief is crucial because it fulfills the requirement for salvation as expressed in Romans 10:9, where confessing Jesus as Lord leads to salvation. Moreover, true belief transforms our lives, motivating sincere worship, obedience, and the manifestation of God's work in us, confirming our relationship with Him.
