Who we are, our salvation, our place in the world, the reason for our existence is all based on a connection to God. And as a creation of a being who is Himself community, He has made us to be in, live in, thrive through community.
Learning to imitate what is good means that we have to spend time with the one who is good. We have to welcome God into our homes, our lives. He won't force his way in. He waits to be invited in.
