Lesson two is reflect it. Lesson three is live it. This is where community begins. It begins in the common discovery of God and of God's love. But it really begins in the commandment to love one another.
Community is where love is experienced.
It is where love is tested, and refined, and celebrated, and trained, and rebuilt. Community is where we find out if all this stuff is true, or not. We can talk a lot about God's love, but it can all be up in our heads. When we live in a community, when we commit ourselves to each other, instead of being generalized, love gets really specific. Years ago I ran across a saying in German.
