"They shall see his face."
When we look into the face of our Lord and he looks back at us with infinite love, we will see in him the fulfillment of everything that we know to be good and right and desirable in the universe.—Wayne Grudem, Systematic Theology, 1164.
In the face of God we will see the fulfillment of all the longing we have ever had to know perfect love, peace, and joy, and to know truth and justice, holiness and wisdom, goodness and power, and glory and beauty.
When we finally see the Lord face to face, our hearts will want nothing else.
"Whom have I in heaven but you?"
