When God created us he had an Idea of a perfect relationship , communion with him. But we blew it. We discovered Sin, along with it came shame and a whole slew of other dysfunctions that were never meant for us. So now what do we do? 
Well he actually had that covered as he knew all along we would choose to be our own Gods. Through the perfect life and the sacrificial death of his son (the lamb of God) Provided a way for that relationship to be restored.
Why? Not that he NEEDED US as this would cease him from being God. That He WANTED US.Because he is love.
