In my humble opinion, and I could be wrong, but I think he was contributing to the original post. The original post is titled, "where is the love", and at the end of the post says, "And above all show the love of Jesus." In Mitspa's post he quotes John 14:22, and makes bold Jesus saying, "If a man love me he will keep my words."I'm not sure what point is being made with this quote, but I'd love to know.
So, I believe how they relate is OP is saying show the love of Jesus, and Mitspa is quoting a verse where Jesus tells how to show love to Him. *hugs*
