How do we know that Jesus is the Christ according to the Bible?

The recognition of Jesus as the Christ is foundational in Christian doctrine. In John 20:30-31, it is stated that the purpose of the Gospel is to make known that Jesus is the Christ, the Son of God, so that by believing, one may have life in His name. The apostle John reinforces this by emphasizing that anyone who denies Christ's incarnation is an antichrist, highlighting the centrality of this truth in faith. Believing in Jesus as the Christ is not merely intellectual assent; it is an acknowledgment of His divine nature and a relational trust that leads to transformation and eternal life.
