Why is believing Jesus Christ as the Son of God important for Christians?

For Christians, believing that Jesus Christ is the Son of God is vital because it is the foundation of our faith and the bedrock of our salvation. As highlighted in John 20:31, belief in His divine nature is essential for obtaining eternal life. Without this belief, there is no true repentance or turning to God, as one can only turn to someone greater than their idols. Understanding Jesus as the Son of God assures believers of His authority to save, rooted in His identity as both divine and human, making Him the perfect mediator between God and man.
