All of us subconsciously process what we read and hear through our own perspectives on language. That perspective is often based on culture and personal experience, as well as the slang and verbal hyperbole of the era in which we were adolescents. That unique take on language can cause stumbling blocks and miscommunications even with people we know well, so when we are applying it to the words of people who lived long ago and far away, in a completely different culture, it can make understanding what is being said difficult.
Rabbi on the Mount helps us bridge the gap between ancient Israel and today so we can hear what Jesus was actually saying in the Sermon on the Mount. This perspective gave me a whole new understanding of Jesus' sermon, one which helps me know how best to obey what the Lord was telling us to do that day. I can't recommend this enough.
