This is a beautiful, simple, high impact, Gospel illustration that's very easy to do.  Three silk handkerchieves are show, yellow (earthly accomplishments and "trophies"), black (failure, shortcomings, sin), and red (the Blood of Jesus.  It is explained that most people base their righteousness (right standing with God) on their accomplishments and failures.  What we should do, and must do, is to look away from our works and look toward the Cross of Christ.  All three scarves are dropped into a change bag or other utility prop.  "When we look away from our works and place faith in His blood, He washes it all and moves into our lives and hearts!" When the silks are pulled out they have blended together into a HUGE 36" portrait of Jesus!
