In my first book, The Midrash Key, I argue that many of Jesus’ (Yeshua’s) teachings—including sections of The Sermon on the Mount—find their origin in Deuteronomy or Leviticus. Our Lord gathered a large crowd together for the Sermon on the Mount, so we know it was much longer than the eleven-minute summary found in the Gospel According to Matthew. Two hours would be the bare minimum, but He probably taught all day. We only have the summary the Gospel writers preserved.
Today I am suggesting that another part of The Sermon on the Mount (Matt. 6:1-4, 16-23) finds its origin in Isaiah 58:1-8. I believe Jesus commented on and developed themes from this text. See if you agree with me.
The theme of this section is “God detests mechanical religion.” In other words, God does not want our lip service, He wants our hearts, our selves. He has no tolerance for mechanical religion; He will not be controlled or manipulated. We can obey Him, but we can do Him no favors. We owe Him total allegiance by birth.
How we live on a daily basis is also a spiritual issue. When it comes to being a follower of Yeshua, we are not allowed to segment ourselves. We may be more “secular” in our jobs or among our lost family members than we would be with fellow believers, but we still must adhere to Christian ethics and conduct.
