We take that item that was considered worthless and completely break it down. It is then melted down to its purest form and made into a new product.
In the same way, Jesus sees value in people that the world has given up on. When someone turns themselves over to Him to be recycled, He makes them into a new person. II Corinthians 5:17 says, Therefore, if anyone is in Christ, he is a new creation; the old has gone, the new has come!
