Searching for something you already have in Christ?

Below is another quote from Tullian Tchividjian from One Way Love:

Unfortunately, this (story about looking for keys that are in our pockets) is the way so many of us Christians live: searching high and low for something we already have, trying to earn something we've already been given, forgetting that everything we need, we already possess in Christ. Or perhaps it's not that we forget, perhaps it's that we prefer having the "elf on the shelf" keeping track of our every move. It makes us feel safer. We would rather work under duress than live under freedom. Yet this is precisely why we need to hear, each and every week, the basic good news that because Jesus' finished work, we already have all of the justification, approval, significance, security, freedom, validation, love, righteousness, and rescue for which we desperately long--and look for in a thousand things that are infinitely smaller than Jesus.
