So the vision of God must ever remain invisible to unrepentant sinners who by their own actions deprive themselves of the eternal bliss and joy which that vision bestows, and which in the end is the only happiness which the Universe provides.

We are all sinners, but if we are repentant sinners who seek to be transformed by Our Blessed Lord into saints of God, we will eventually receive the reward of the pure in heart – we will see God, and see him for ever.
