What is the point of anything, is a good question.
A good answer for Christians is that what we do is a foretaste, a foreword, a good go, an early attempt, a sign, instrument, and portent of the world to come. It will all be thrown away as juvinilia (the early output of the creatives). But like juvinilia it is connected, even contiguous, with all that is to come. Here are some metaphors:
- We are seeds, due to perish, but also a kind of Noah’s ark bearing extracts from the old world into the new. Into the marigold seeds that I save for next year are poured a whole marigold’s summer of life. When we go to our grave, we take our marigold summer with us, into the next life. When the cosmos dies, somehow, the same happens. So will it be with the resurrection of the dead. The body that is sown is perishable, it is raised imperishable; it is sown in dishonor, it is raised in glory; it is sown in weakness, it is raised in power; it is sown a natural body, it is raised a spiritual body. (1 Corinthians 15:42-44)
2. Treasure and fine linen and the best of culture. The best of our earthly service is somehow returned to us, or to the cosmos, when the New Creation comes:
..Store up for yourselves treasures in heaven, where moths and vermin do not destroy, and where thieves do not break in and steal. For where your treasure is, there your heart will be also. (Matthew 6:20-21)
For the wedding of the Lamb has come,
and his bride has made herself ready.
8 Fine linen, bright and clean,
was given her to wear.”
(Fine linen stands for the righteous acts of God’s holy people.) (Revelation 19:7-9)
And he carried me away in the Spirit to a mountain great and high, and showed me the Holy City, Jerusalem, coming down out of heaven from God…26 The glory and honor of the nations will be brought into it. (Revelation 21: 1o, 25)
This gives us a reason for every temporary act. We live in a world of death, and ends, and shadows, and half-built things, and things that fall down. But we build anyway, love anyway, serve anyway, invent anyway, create anyway, work anyway, because the best of it, whatever it is, we will see again and know it as our own, all spruced up and transformed through Christ.
