How do we know Jesus is the true God and man?

The truth that Jesus is both fully God and fully man is rooted deeply in Scripture, specifically in Colossians 2:9, which states, 'in him dwells all the fullness of the Godhead bodily.' This declaration is supported by numerous prophecies throughout the Old Testament, such as those in Psalm 40 and the prophetic announcements of the virgin birth, which affirm that Jesus possesses a sinless human nature. Furthermore, His self-identification as one with the Father (John 10:30) confirms His divine nature.

Additionally, Jesus' life and ministry demonstrated His divine authority. He performed miracles, forgave sins, and ultimately triumphed over death, which reinforces His identity as God incarnate. The union of divine and human in Christ is not merely a theological assertion but foundational to the believer’s faith. Through this union, believers can relate to God in a personal and transformative way, as Jesus mediates our relationship with the Father and reveals divine grace and truth.
