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

Believing that Jesus is the Son of God is crucial for Christians as it forms the foundation of their faith. The sermon emphasizes that salvation is not contingent upon personal works but on understanding and accepting who Christ is—God the Son. This belief ensures that one is part of the family of God, as seen in John 1:12, where those who receive Him are given power to become sons of God. Thus, knowing Christ's true identity allows believers to have assurance in their salvation and confidence in their relationship with the Father, ultimately nurturing a life of faith.
