Is it your goal to live as close as possible to the way the early church lived? Are you making sure you don't eat any food offered to idols, wearing a head covering (if you are a woman), or treating your slaves well (if you are their master), or obeying your master (if you are a slave)? Are you making sure that women are silent in your church and have no place of authority? Or is that pretty much entirely missing the point?
It's easy to see the specific things the Bible talks about. Some things that may well have been really important to people two thousand years ago. But don't enter into life much today. It's harder to get down into what is below the surface. It takes more energy, more thought, more heart. It takes being willing to find out what God is like. Instead of finding a verse that might fit your favorite theory, it involves truly digging. You might discover that the God you have created isn't at all like the one you discover. You might discover that God is much more loving than you figured. That he loves a much wider assortment of people than you want him to. Take a look as Jesus. Tell me one group of people that he didn't love. That he didn't accept. That he had any harsh words for. Well, yes, there is one group. But you might not want to look to close at them. You might recognize a bit of your self-righteous side. But you won't find any kind of segregation, any 'insiders' and 'outsiders'.
Back to trying to live like a first century Christian. The world doesn't need someone who is out of touch with their reality. If people are going to be attracted to Jesus, it will be through people who understand life today. Who have discovered that the message of Jesus has something to say in today's world. That this Jesus who showed he loved everyone 2000 years ago still has that kind of inclusive love today. That he still says; “Neither do I condemn you.” And that his followers echo that sentiment.
Life has taken me from the rather predictable working year after year and not feeling fulfilled to serving with Youth With A Mission as a missionary in my homeland of Canada. I am presently active in Victoria, with responsibilities and interests in our YWAM office, and out on the street. (and feeling more fulfilled than at any time earlier in my life.)
