Here's something I came across that made me think:
"Since we already have God's image, why can't we express Him? We may say that the man created in the image of God resembles the photograph of a person. Suppose you take a photograph of Brother John and show it to others saying that this is Brother John. In a sense, you are correct, for that is Brother John. However, the photograph is not the real Brother John; it is Brother John in a picture. Although the picture reveals the features, style, and the person of Brother John, it does not have the life of Brother John. It can show something of Brother John, but it cannot express him. The only way for the photograph to express Brother John is for it to have his life.
"Man was created in the image of God, but he was like a photograph showing something of God without having the life of God. Although man was in the image of God, he did not have the life of God. God intended that man should partake of the life indicated by the tree of life. Man failed to do it. Today, by believing in Christ, we have been brought back to share in that life. We all have received eternal life. Thus, there is no other way for us to express God in His image and to represent God with His authority except by sharing His life. This is confirmed by many verses in the Bible."
