Does Seeing God's Glory Demand a Mediator?

We discuss Exodus 33: and Moses asking God, "Please show me your glory." And God said, "I will make all my goodness pass before you and will proclaim before you the name, 'The LORD', and I will be gracious to whom I will be gracious and will show mercy on whom I will show mercy. But,' he said, 'you cannot see my face, for no one shall see me and live.'" We discuss Hebrews 3:1-6 which discusses that Heb 3:3 "Yeshua/Jesus has been counted worthy of more glory than Moses-as much more glory as the builder of a house has more honor than the house itself." We discuss Yeshua/Jesus as a mediator of more of God's glory as we are progressively conformed to his image and enter into communion with him as a new man and together as a new humanity, the unified ekklesia/church or body of Messiah.
