Mission, or evangelism, is not just another program that the church carries out. The church is mission. Yes, the church gathers as people being called out (ekklesia) of the world. But the church is at the same time being sent out (apostolos) into the world. The church certainly must be called out from the world, but it also must certainly go back into the world. We are to be holy, set apart and different in our character than those who do not know God. But, we should also refuse to believe the lies the “churched” culture tells us: avoid hanging out with the people in the world because you will be corrupted. We also need to reject the lie that we have to create our own Christian sub-culture and insulate ourselves from the big, bad world. Mission demands that we follow Jesus, friend of sinners, by being immersed in relationships with those far from God, and thus, bring light to lost people in dark cultures. We are called out, but we are sent. It is only in the context of being sent do the metaphors “salt of the earth,” “city on a hill,” and “light of the world” make sense in describing the church. We are to be people who have been encountered by God through the gospel, and then we are to enter the world with the gospel.
