I have two brothers - one older and one younger. Growing up, we fought all the time - it always seemed to be two against one. I don't know how my parents managed to stay sane after saying for the bazillionth time "quit fighting with your brother!" Miraculously, we are great friends as adults and, even though we all live in different parts of the country, it's always wonderful spending time with them. Our years together, shared genetics, and common experiences have given us this comfortable familiarity that allows us to be goofy, serious, sentimental, argumentative, and even unreasonable with each other. I love them and they love me. I hope that everyone has siblings or cousins or even friends who they can just be family with.
That's the way Jesus wants us to feel about Him. Yes, He is Lord, but he's also chosen us to be his family. He wants us to feel comfortable enough to be ourselves with Him. He wants you to share yourself with Him.
