The cross being left is a sign of hope; light shining in on a dark situation. A statement of strength in Christ and a hope in the hereafter. Though heaven and earth will pass away, His words will never pass away. We live in the age of grace and He do7se̵n;t want us to forget that. Though many things seem important, nothing is more important than Christ and what He did for us on the cross.Or it could be a coincidence that the cross is left standing and it means nothing at all.
