Ummm misquote of scripture to start with ... ..but the youth said he had kept all the commandments and Christ still sent him away ..
One very important thing to remember when reading the gospels is they are retrospective ...they reflect the Old Testament laws that Jesus lived under and kept perfectly for the saved ...
How is it a misquote? That verbatim from the King James, Matthew 19:17.
but the youth said he had kept all the commandments and Christ still sent him away ..
No, he hadn't kept the first.
