Why must I prove my love to God?

A very good question. They said, what kind of God is it? What kind of God is it that demands proof of my love for Him? It was a child actually. She came to my house for dinner along with her parents. So she said, but why should I have to prove my love for God? Why can't He just, I don't know what, something. So why do I have to turn towards him? So I said to this child that suppose you had a partner, suppose you had a partner who never called you, who never sent you a message, who never came and met you, who never did anything for you, who never turned towards you in any way, never remembered you, never remembered you and then he said to you okay why do I have to prove my love to you
