Although you need to understand that when God says he loves everybody, it doesn't mean we can just go do whatever we want and he will be happy with us.
Now i'm not saying he doesn't love us, because he does. But he still gave us rules and a list of things we shouldn't do. Such as the ten commandments.
So he created us, gave us everything in our life (food, water, shelter) and told us what we should and shouldn't do. So OBVIOUSLY he's gonna be mad if we go and sin after he told us not too. He blessed us so much and we repay him by spitting in his face? Thats not good.
