How do we know that Jesus is equal to the Father?

The equality of Jesus with the Father is a profound truth of Christian theology. In John 14:9, Jesus says to Philip, 'He that hath seen me hath seen the Father.' This statement underlines that Christ embodies the fullness of God and that His nature is divine. Colossians 2:9 reinforces this by stating, 'For in him dwelleth all the fulness of the Godhead bodily.' Understanding Christ's equality with the Father is crucial to grasping the nature of the Trinity and how God reveals Himself to humanity.
