How do we know Christ is God according to the Bible?

The doctrine of Christ's divinity is distinctly supported by Scripture, particularly in verses such as John 20:28, where Thomas addresses the risen Christ as 'My Lord and my God.' This declaration not only acknowledges Christ's divine nature but also reflects the belief that Jesus exemplifies the fullness of God within human form, as stated in Colossians 2:9. This verse explicitly declares that all the fullness of the Godhead dwells in Him bodily, asserting His complete divinity.

Moreover, the theological idea that God cannot be separated from Christ is crucial. As Tobias Crisp notes, whatever we understand of God must be through the lens of Jesus Christ. This interdependent understanding reinforces that Jesus is not merely a representation of God but literally embodies all that God is. Understanding Him in this way is vital for a sound theology, as it clarifies the relationship between the Father, Son, and Holy Spirit and emphasizes the singularity of God as revealed through Christ. Therefore, the biblical evidence points decisively to Christ as true God and true man, necessary for a proper grasp of Christian faith.
