We aught to do even more at walking out true, biblical local church life. There is such a great and dire need. Small groups is a way to model biblically healthy local church life.
For even as the body is one and yet has many members, and all the members of the body, though they are many, are one body, so also is Christ. For by one Spirit we were all baptized into one body, whether Jews or Greeks, whether slaves or free, and we were all made to drink of one Spirit.
1 Corinthians 12:12-30
