God’s mission in this world is the Redemption of all things: humanity, the world… everything. Creation and all that was in it was broken when sin entered the world, but God sought our healing by sending His Son, Jesus, to take the consequences of sin on Himself in our place. When we receive Christ’s offer to trade His righteous life for our broken ones, we find… Redemption.
Our past, our present, and our ultimate future are all a work of God’s Redemption.
This is God’s mission in the world, so as His church, it is our mission, too.
