1 Corinthians 13:12
For now we see in a mirror dimly, but then face to face.
When the world thinks of Heaven it thinks of beautiful scenery, or various perks, or something vaguely called "happiness." To be sure, Heaven will be the most beautiful place imaginable (and it will indeed involve a New Earth, not simply vaporous spooks floating in the Vast Nowhere). But that's not what captures the biblical imagination. Rather, the supreme joy of Heaven is that we shall see God Himself "face to face." That is the essence of beatitude. Jesus, in the Beatitudes is, so to speak, training our eyes to see the face of God in the poor, the mourning, the meek, the persecuted, and all the others whom He names "blessed." If you want to see God's face, that is where you must look.
