During my teen years, when I had a rebellious, angry heart, I once encountered some one who tried to tell me that I was "one of a kind," and specially made by a God who loved me. At the time, I couldn't have been more unimpressed ... or so I thought. Not long after that, by the grace of God I did come to believe.
Psalm 139 is an amazing psalm that reminds us that we are uniquely created, and that we have a God who is totally aware of exactly who we are, what we are doing, and what we are thinking - even before we do. I love the part where is says, "you hem me in-behind and before..." That leaves little room for doubt that He is a God who is near, and who cares.
