One of the first things investigators do when an aircraft crashes is search for the "black box", because it records and reveals every piece of data that might explain why the plane went down. We all sin, and sometimes we try to cover it up, but there's a "black box" in our lives recording everything we do, and eventually it will be made known. God calls us not to hide from Him, but to come clean before Him in repentance and allow Him to change us from the inside out.
