Human incarnation Vs statue

What is the importance of human incarnation over a statue in our worship?

A statue cannot test your real essence in the sacrifice. When you offer food to a statue the sacrifice is only by words and by mind but when you sacrifice the food to the human incarnation the sacrifice is real because the human form of the Lord eats the food. Thus the reality of the worship comes out only when the Lord is in human form. Sakthuprastha was tested by the Lord in human form and not by the statue.
