I read what the Lord Jesus said in that verse and i believe him . ( Yes I'm a gentile ,saved by believing the Gospel of grace .By his death ,his blood and his life ( resurrection) None of that happened when he said those words . God did not stop speaking in the four Gospels . You must keep reading past them and onto the book of Acts ,leading to Paul's letters .Based on this scripture, and assuming you are a gentile, do you use this scripture to deny Christ as your savior?
