What the Apostle Paul meant by a God not made of shrine or human hands

Acts 17:24-28 The God who made the world and everything in it, he who is Lord of heaven and earth, does not live in shrines made by human hands, nor is he served by human hands as though he needed anything, since he himself give to all mortals life and breath and all things.  From one ancestor he made all nations to inhabit the whole earth, and he allotted the times of their exitence and the boundaries of the places where they would live so that they would search for God and perhaps grope for him and find him though indeed he is not far from each one of us.  For in him we live and move and have our being as even some of your poets have said.
