In the early church, the Christian community did a lot of things that seemed kind of crazy. They sold all their possessions, they lived together, and they took care of all the needs of everyone around them.
Acts 2:42-47 says:
"They devoted themselves to the apostles’ teaching and to fellowship, to the breaking of bread and to prayer. Everyone was filled with awe at the many wonders and signs performed by the apostles. All the believers were together and had everything in common. They sold property and possessions to give to anyone who had need. Every day they continued to meet together in the temple courts. They broke bread in their homes and ate together with glad and sincere hearts, praising God and enjoying the favor of all the people. And the Lord added to their number daily those who were being saved."
I find it interesting that in this kind of community that modern day Christians would find "cultish," people were being saved daily. We Christians in 2013 barely see any salvations on Sunday mornings, yet these people were seeing them every day. It makes me ask the question, "Why not us?"
I believe the answer to that question is a lack of community. We go to church on Sundays and Wednesdays and pass by people every week that we never speak to. We avoid eye contact and stick to our clicks and leave as lonely as we came. I'm not saying that the answer is to all live together in some commune, but we have to start becoming the community that God intended us to be.
John 17:22, 23 says:
"I have given them the glory that you gave me, that they may be one as we are one— I in them and you in me—so that they may be brought to complete unity. Then the world will know that you sent me and have loved them even as you have loved me."
If we can't be united, then we have no voice in this world. All the best sermons and music and illustrations are meaningless if we do not have unity among ourselves. It is in unity that we can take time to get to know the people that we walk by week after week. We can share one another's burdens, our successes and our failures. We can lift each other up. And when we are united like that, the world will take notice, and we will start to see real growth in our community.
