Although we live on a cursed earth, we also live on a covenanted earth.
This is God's earth, and God is covenantally committed to its survival, just as later revelation will show us that God is also covenantally committed to its ultimate redemption.
Our mission takes place within the framework of God's universal promise to the created order.
The rainbow promise spans whatever horizon we can ever see.
