Made in God's Image

In the sermon today the pastor talked about how we attempt to make God in our own image. The pastor argued that this is wrong because we are made in God's image, not God in our own.

However, I wonder that
if we are made in God's image
then we are images of God
and
since no person has seen God in a very long time and no one really remembers what Jesus looked like,
then all we can do is look at each other and try to piece together an image of God reflected in those we see.

What can we learn about God in the faces of our neighbor? How can we discern what is God's image and the image of crap? What role does scripture/the Bible play in revealing God? Scripture is God revealed in the accounts and truth of the people of God in that time and place?
