Don't get comfortable.
I read a post from John Piper's ministry this week about the need to feel uncomfortable on Sundays. You can read the full article here. Basically, the author encourages us to look out for people who are alone at church—whether they're new or have been coming for a long time.
I highly recommend reading the whole article, but if you only have enough time to read this little post, I just want to say, "Let's do it!" Let's make Riverstone a place where people aren't alone. When we're together, if somebody is alone let's make sure they don't remain alone.
God called us to love one another. One of our goals at Riverstone is to love our neighbors and community and I believe that begins when we're together on Sunday morning. Our friendships won't suffer because we've taken the time to talk to somebody else. We won't lose touch because we're sitting with somebody who would otherwise be sitting alone.
God created us for community. Let's plan on being a community from the very beginning. Reach out to people you don't know. Sit with them. Invite them to lunch. After a couple weeks being uncomfortable might not feel so bad after all.
