What does the Bible say about the deity of Jesus?

The Scripture explicitly declares the deity of Jesus in John 1:1-5, stating that 'In the beginning was the Word, and the Word was with God, and the Word was God.' This foundational truth affirms that Jesus is not merely a prophet or a good teacher, but God Himself manifest in the flesh. John aims to eliminate any doubt regarding Jesus' divine nature by consistently presenting Him as the God-man, emphasizing that His life and death hold eternal significance precisely because He is both fully God and fully man. This understanding is essential for grasping the full weight of the Gospel and our need to believe on Him for salvation.
