Weight of Glory by C.S. Lewis is a beautifully crafted, deeply poetic, meditation on the glory that awaits all Christians in eternity.

Lewis describes glory as God's approval for us, because our deepest pleasure is found in making Him happy. (This is almost the reciprocal side of the WSC, "man's chief end is to glorify God and enjoy Him forever.") Because of Christ, God is infinitely pleased with us. His pleasure--this glory He gives us--climaxes in our oneness with Christ.

There is a beauty and glory shining through our life experiences (a song, a sunset, a movie), teasing us to become a part of it. Right now we cannot. Creation can only taunt us now. One day God's glory will beam through us more gloriously than anything we've ever sensed in the sunset or a song. He will say to us, "Well done, good and faithful servant. Enter into the joy of my Lord."

If I find in myself a desire which no experience in this world can satisfy, the most probable explanation is that I was made for another world. If none of my earthly pleasures satisfy it, that does not prove that the universe is a fraud. Probably earthly pleasures were never meant to satisfy it, but only to arouse it, to suggest the real thing...
Mere Christianity, on "Hope"

I think earth, if chosen instead of Heaven, will turn out to have been, all along, only a region in Hell: and earth, if put second to Heaven,to have been from the beginning a part of Heaven itself.
