The New Attitude website has recently featured a number of blog entries and articles having to do with church involvement and membership (you can find a number of those articles on the local church here). Their website, and especially the article and audio sections, contains great resources.
The following is an excerpt from an article by Mark Dever (it actually comes from his new book “What is a Healthy Church?”).
Healthy churches, we have said, are congregations that increasingly reflect the character of God. Therefore, we want our earthly records to approximate, as much as possible, heaven’s own records—those names recorded in the Lamb’s book of life (Phil. 4:3; Rev. 21:27).
A healthy church aspires to receive and to dismiss individuals professing faith, just as the New Testament authors instruct. That is, it aspires to have a biblical understanding of membership.
Biblical Membership Means Commitment
A temple has bricks. A flock has sheep. A vine has branches. And a body has members. In one sense, church membership begins when Christ saves us and makes us a member of his body. Yet his work must then be given expression in an actual local church. In that sense, church membership begins when we commit to a particular body. Being a Christian means being joined to a church.
Scripture therefore instructs us to assemble regularly so that we can regularly rejoice in our common hope and regularly spur one another on to love and good deeds (Heb. 10:23–25). Church membership is not simply a record of a box we once checked. It’s not a sentimental feeling. It’s not an expression of affection toward a familiar place. It’s not an expression of loyalty or disloyalty toward parents. It should be the reflection of a living commitment, or it is worthless. Indeed, it’s worse than worthless; it’s dangerous, as we’ll consider in a moment.
Biblical Membership Means Taking Responsibility
The practice of church membership among Christians occurs when Christians grasp hold of each other in responsibility and love. By identifying ourselves with a particular local church, we are telling the church’s pastors and other members not just that we commit to them, but that we commit to them in gathering, giving, prayer, and service. We are telling them to expect certain things from us and to hold us accountable if we don’t follow through. Joining a church is an act of saying, “I am now your responsibility, and you are my responsibility.” (Yes, this is countercultural. Even more, it’s counter to our sinful natures.)
Biblical membership means taking responsibility. It comes from our mutual obligations as spelled out in all of Scripture’s one another passages—love one another, serve one another, encourage one another. All of these commands should be encapsulated in the covenant of a healthy church.
