I am increasingly convinced that Jesus’s Sermon on the Mount (Matthew 5-7; see his corresponding Sermon on the Plain in Luke 6) is essentially off the radar for many Christians, not a real consideration at all. And the ironic thing is that Jesus ends that sermon (both sermons) with the analogy of the man who built his house either on the rock, or on sand. That this teaching from our Lord is actually foundational.
I believe our heart by the Holy Spirit is often better than our heads. Christians often have a kind of sixth sense, so to speak, by the Spirit, so that they do much better in life, akin for example to what our Lord says about loving our enemies, etc., in the sermon. And those whose theology actually takes it out of consideration can be grace-filled, loving believers. But good theology, Biblical interpretation, and God’s written word matters. We need to be in all of it from Genesis through Revelation. And certain passages need to be underlined and probably emphasized depending on the culture in which one lives. Surely the Sermon on the Mount fills a needed dearth among many Christians in the United States.
We must beware of seeking to apply these words of our Lord to nations and unbelievers. Rather, they are for believers and followers of Jesus. But we must apply them, indeed. We can respect and want the US Constitution and foundation for this nation to be adhered to for the continuation of this liberal democratic state, liberal not in the way spoken of today, but according to what was meant at the nation’s inception, though much of what carries over from that might logically follow. But for us in Jesus, we need to be in all of the word, and Jesus’s Sermon on the Mount should certainly be a staple of our thinking and living. Along with my psalm, Old/First Testament, and New/Final Testament reading, I read from either the Sermon on the Mount, or the Sermon on the Plain, daily. Hopefully more and more of that will soak in and make a difference. Something for the entire church to help make the difference that’s needed in our lives and witness in and through Jesus.
