Think about it: God was perfectly happy in the Trinity of Love. So the only reason He created the world is so that man, the only creature God loves for himself, could exist. Despite the fact that Adam and Eve sinned and destroyed His plan, God sent His Only Begotten Son to make us His children and give us life in abundance.
So I think we can rightly believe that we are truly important to God. He bought us at the price of His Son's Blood.
