Is it in the Bible?. ( Matthew 22 v 29 )

Recently on holiday in Malta with my wife and brother-in-law,and we passed a group of people wearing a little tag with the words on it ,'Love never fails''.Out of curiosity I asked one of them if they were a church,he replied they were, Jehovah witnesses .We moved on our walk and then sat down for a rest and to enjoy the sea view,I noticed a couple not for from us sitting having a bit lunch, I could tell they were JW's so I made my way to them prayerfully. I opened up a conversation with them ,they were a nice couple, they had their little boy with them,they come from Macedonia,and were  attending a conference,inviting us to go which we declined.They were surprised that I studied my Bible,mentioned how few people did,which is true.Our conversation ended by me asking them two questions,( 1 )Was the Christ that they believed in , the Christ of the Bible ?. ( 2 ) Was the salvation they believed in,the salvation that was in the Bible?, and of course the answer to the two questions is ,it is not.
