According to the Hebrew Scriptures, the Christian Old Testament, mankind was created in the image of God. This is a unique idea to the Ancient Near East where the gods typically were thought to be completely separate from humans. In fact, in the ANE culture, humans were created so they could serve the gods. They would harvest food and offer sacrifices so the gods could be nourished without having to do the work themselves. For the Hebrews and Christians, God created humans to represent His name and His character to the rest of creation.
I always loved this unusual action by God to allow humans to represent His name but I have also always questioned it. Frankly, I think God could've chosen something more reliable than humans to represent Himself on earth but that is just me. Now, the question we have to face is "Because we represent God's image to creation, what image are we projecting?"
Do you project an image of God as a disinterested, self centered being? Do you show the world that God's image is one that is a jerk to others and unwilling to forgive? Perhaps you reflect an image that is gracious, that is loving, and that builds others up. Whatever image you project, as a follower of God you are representing His name so lets be lead lives that are mindful of the true character of the Creator.
