According to John's account of the resurrection, Mary Magdalene told Peter and John the tomb was empty. They, then, ran to see for themselves. John 20:6b-7 says, "He (Peter) saw the strips of linen as well as the burial cloth that had been around Jesus' head. The cloth was folded by itself, separate from the linen."
In a Beth Moore Bible study several years ago, I learned that during Jesus' time, it was customary for a carpenter to fold his work cloth and leave it on the finished piece, so the one who had hired him would know the work was finished.
Did Peter remember Jesus' last words on the cross? "It is finished." (John 19:30)
If so, this folded cloth would have sent them a clear message, and it provides a clear message for us today. Jesus is everything we need Him to be because He has done all He needs to do for us.
Happy Resurrection Day!
