Jesus gives us the most radical ethic of love that’s ever been put forth: “Turn the other cheek.” This ethic has been criticized and disregarded, but no one ever says the reason is because it’s too low or vile or unworthy. They always say it’s too high, too lofty.
The reason it seems so lofty is it’s a whole new dimension. The love ethic in Matthew 5 is part of a package. The package is that Christianity itself is actually an interconnected set of radically altered relationships. A new relationship with God creates a new relationship with yourself, creates a new relationship with others. They can’t be separated. They rise and fall together, and you can’t have one without the others. 
Let’s take a look at those three aspects. As we move through this passage, we’ll see 1) the understanding of the self, 2) the relationship with others, and 3) the root of it all: a new relationship with God.
