Community

Certain things just come naturally in groups. You never see one grape on a vine, or one grit in a bowl. Oprah always comes with Gail; Bert is lost without Ernie; and Me without Heidi? … well, it just seems a bit strange. It's just not natural to be alone. Community is important.
In Genesis 2:18 sin had not yet entered the garden, yet as Pastor Kyle Ray points out, "The Bible says that there was something that was 'not good'" Read it for yourself:

It is not good for man to be alone. I will make a companion to help him.

And I believe that's the point. Anyone who would fall into the category of 'community' (friends, family, spouse, mentor, co-worker) has been placed in our lives for help.

Let me give you another example from good ole Mother Nature: Sequoia Redwood trees. These trees are so ginormous,(that's a 1st grade word) they require a whole bunch of water to survive. Therefore they have a very, very shallow root system. Most of their roots lie just below the surface of dirt so as soon as the rain water soaks in, - boom! The roots are there to soak it up.
Only one problem; Roots are suppose to support plants! With such a shallow root system, you'd think that one good storm would blow through and…TIMBER! Down they'd go! Right? Wrong! These trees avoid an untimely death by growing in… community. (That's right, don't be shy. Just shout it out when you know the answer.) The trees grow so close together that their roots intertwine. Above, below, through, and around, they create one massive web of roots that work as support. So when storms blow through, they literally hold each other up! How cool is that? So see where I'm going with this don't you?
When we have "storms" in our lives, it's our community that holds us up. Look at some more cool verses about the support of communities in the Bible:

When others are troubled, we will be able to give them the same comfort God has given us…For when God comforts us, it is so that we, in turn, can be an encouragement to you. Then you can patiently endure the same things we suffer. (2 Cor.1:4)

Now I want to tell you, dear brothers and sisters, what God in his kindness has done for the churches in Macedonia. Thought they have been going through much trouble and hard times, their wonderful joy and deep poverty have overflowed in rich generosity. For I can testify that they gave not only what they could afford, but far more. And they did it of their own free will. They begged us again and again for the gracious privilege of sharing in the gift for the Christians in Jerusalem. (2 Cor 8:1)

And all the believers met together constantly and shared everything they had. They sold their possessions and shared the proceeds with those in need. They worshiped together at the Temple each day, met in homes for the Lord's Supper, and shared their meals with great joy and generosity,- all the while praising God and enjoying the goodwill of all the people. And each day the Lord added to their group those who were being saved. (Acts 2:44)
