The current world's population is estimated at over 7,080,000,000 people. Depending on your "origins" beliefs you can estimate from that how many people have ever lived on the earth over its life. It is a stunning number and yet, as the man performing a wedding I attended last weekend said, each and every one is different—no two are ever alike—and we are all made in God's image.
Setting aside the theological differences about what it actually means to be in His image, we can say that every person who has ever lived is different and yet every person reflects God's image in some way. Isn't it an awesome comfort to know that our God is so big and so vast and so unfathomable that billions upon billions of people can each represent a facet of Him and we still don't have a complete picture of Him?! I am so glad that God is so huge. I wouldn't want to trust my life to a god who was so small I could fully grasp and understand Him. It is so comforting to know that the God I trust and serve and depend on is so big that I will spend eternity discovering more and more of the riches of the knowledge and mystery of Him.
