Becoming A Church Member

Why should it matter if a person is committed to a local church if they are a Christian and I attend a church service on occasion? I would argue that the importance of membership in a local church is the same argument for the importance of marriage over cohabitation. While several couples enjoy the beautiful things that a married couple gets to do: live together, make a home together, engage in marital intimacy, have children, share confidences, etc. These are activities of marriage.
