Look at these two boxes. Which one of them is more like your faith?
Faith can be like a beautiful, ornate box that we put up on the shelf, look at every now and then and find comfort that it's there, occasionally dust it off, but never really open it to see what's inside.
Or, Faith can be like a rough looking, beaten up foot locker that is filled with all kinds of beautiful treasures, that when we open it fills our home with beauty and fragrance and faith and hope and love and joy and peace and so much more, like Pandora's box but in a good way. Here's the thing - - foot lockers belong to soldiers. When our faith is something we fight for, and fight with, when we embrace the struggles that come with not getting all of our questions answered, when we walk with Jesus through the darkest places of our life and trust him to lead us through because we simply cannot even see to put one foot in front of the other, when we trust him to guard our heart because we can't even guard our own hearts successfully because they lie to us, our faith may look on the outside like this beaten up foot locker. It's not always going to be pretty, and it's not always going to be comforting to look at. But when we open it up, it fills us beyond imagination.
I think that's some of what Peter is getting at in these verses. We have no clue really all that is wrapped up in what we have when we are in Christ. He's urging us to find out. If your faith has been like the pretty box, I encourage you to take it off the shelf and let it get beaten up, and open it up and just find out what you're missing.
