Eugene Peterson on the church as a community and a family:
We can no more be a Christian and have nothing to do with the church than we can be a person and not be in a family. Membership in the church is a basic spiritual fact for those who confess Christ as Lord. It is not an option for those Christians who happen by nature to be more gregarious than others. It is part of the fabric of redemption.
There are Christians, of course, who never put their names down on a membership list; there are Christians who refuse to respond to the call to worship each Sunday; there are Christians who say, “I love God but I hate the church.” But they are members all the same, whether they like it or not, whether they acknowledge it or not. For God never makes private, secret salvation deals with people. His relationships with us are personal, true; intimate, yet; but private, no. We are a family in Christ. When we become Christians, we are among brothers and sisters in faith. No Christian is an only child.

To encourage our church members to join small groups (we call it K-Groups or Kaagapay Groups), I preached the sermon entitled Walang Nag-iisa, Bawat Isa May Kaagapay.
