Why is believing in Christ's name important for Christians?

Believing in the name of Christ signifies a deep recognition and acceptance of His identity and work. In John 1:12, receiving Christ is directly linked with believing on His name, which encompasses all that He is—the Son of God, the Savior, and the creator of all things. This belief isn't mere intellectual assent but a transformative faith that leads to being regenerated and granted the right to be called children of God.

Furthermore, as noted in Romans 10:9, confessing with the mouth that Jesus is Lord and believing in the heart that God raised Him from the dead is essential for salvation. This belief gives us assurance and confidence in God's promises, as it aligns with the overarching theme of scripture that salvation is found exclusively in Christ and through faith in Him alone.
