This is a good, theologically sound presentation about marriage but the brief examples it offers feel artificial and it leaves out some important considerations, like the blessings we receive from having the other spouse sacrificing for our benefit (a principle that also applies to intimacy in marriage), the value of one hand washing the other in a relationship, and companionship providing mutual spiritual support between two people who have spent a lifetime together as one flesh.

With its focus on the obligations of self-sacrifice, grace seems to be morphed into law, thereby losing the sense of grace by which only two sinners can live well together.
