One of Jesus' final instructions to his disciples is found in John 13:34-35: "A new commandment I give to you, that you love one another: just as I have loved you, you also are to love one another. By this all people will know that you are my disciples, if you have love for one another.”
Note that Jesus did not say people will know we are Christians by how many churches we build, how many Bible studies we complete, how many prayers we say, or how many people come to our church. His instruction to us is clear: people will know we are Christ-followers when we love each other the way Jesus does.
We need others to help us live lives worthy of God's calling so that people will see the power of God's love in and through us.
Small group fellowship is a way of living out our purpose - both as individuals and as a collective group of believers—to be His church. We share a common foundation of faith and God has called us to live out the implications of that faith in a relational community, in the context that we call a small group.
