Read Jesus through the lens of the reign of God.  He was about turning us in a different direction, away from the direction of line drawing and toward being more responsive to the Spirit within.

I have no special expertise, and I struggle like everyone else.  But I have a sense that I am not in the right direction when I take a literal reading as the standard.  Everything Jesus said about marriage was in reference to the very low bar of Deuteronomy 24:1.  To his audience, what he said called them to a different perspective, one of possibility and promise because it is driven by love of the other.  To take what he said literally deprives his teaching of its essence: the reign of God.  Jesus did not set a higher bar, he called us to a change in direction.  

But if I lack the joy of love -- which does happen -- then a literal reading is what Christ intends for me.  But what Christ hopes for me continues to be the reign of God.
