Jesus said children that believe in me. It is easy to bring a child to believe in Jesus. Jesus now brings a sentence on the offenders saying it would be better that a millstone be hanged about his neck and he were drowned in the midst of the sea. We couldn't manufacture enough milestones for todays offenders.
I am leaving a little room for an offense of body parts. I suppose Jesus didn't actually mean to cut off our hands and feet etc., but He did mean self control. We who know Him as Savior can control ourselves..
