We must receive Christ in Truth with no reservations or doubts.
The Jews could not believe that the man standing in front of them was MightyGod and Saviour. As a result they could not receive His life.
We, who not only acknowledge that Jesus is the express image of His HolySpiritFather, but receive Him into our being, receive the life of the HolySpiritFather.
We receive Christ Jesus as the testimony of the HolySpiritFather and in so doing open ourselves to receive His Spirit, the HolySpiritFather.
