I recently have jumped into the Cure for the Common Life by Max Lucado, so I'm sure you will see frequent quotes from my finds, but this one was a precious reminder to me:
Scan history for your replica; you won't find it. God tailor-made you. He "personally formed you and made each one" (Isa 43:7) No box of "back-up yous" sit in God's workshop. You aren't one of many bricks in the mason's pile or one of a dozen bolts in the mechanic's drawer. You are it! And if you AREN'T you, we don't get you. The world misses out.........God never called you to be anyone other than YOU. But he does call on you to be the best you you can be. The big question is, at your best, who are you?
