I have heard many interpretations about how to deal with Jesus' Sermon on the Mount. In my opinion, the following by Dietrich Bonhoeffer is the best.

Humanly speaking, it is possible to understand the Sermon on the Mount in a thousand different ways. But Jesus knows only one possibility: simple surrender and obedience - not intrepreting or applying it, but doing and obeying it. That is the only way to hear his words. He does not mean for us to discuss it as an ideal. He really means for us to get on with it.
