The local Church is where you can build meaningful community. Community can be messy because it involves flawed, imperfect people. But the local Church is a community where the worship of God is completely normal and encouraged.
It's the only community where you can learn about the true nature of God, and learn about His Love for you. It's the only community where everyone is being encouraged to love you, even though you don't deserve it. And the only community where you can freely love others, even though you know they don't deserve it anymore than you do!
The local Church is the only place where you can have open, honest, loving, lasting community and freely fulfill the purpose of life which is to love God and love other people.
