How do we know that Jesus is God in human flesh?

Jesus' identity as God in human flesh is paramount to Christian doctrine, supported by several scripture passages. Philippians 3:20 highlights our expectation of Christ as our Savior, emphasizing His glorious body, while Colossians 2:9 elucidates that all fullness of the Godhead dwells in Him bodily. This assertion reinforces the unique union of divine and human natures in Christ. Furthermore, in Acts 1:9, His physical ascension confirms that He retains His embodiment, painting a vivid picture of the God-man who intercedes for us and promises to return in the same manner.
