I’ve been reading This Momentary Marriage: A Parable of Permanence by John Piper. It’s available as a free PDF. I was pleasantly surprised at how profound it was. Not just for married couples, but for down-hearted singles (like myself).
Christian marriage literature can be, and has often been, perverted to suit the aims of chauvinistic manipulators. Especially in terms of servitude and gender roles.
This books is not like that. At all.
Piper offers a refreshing, Bible-based understanding of marriage. The focus is rightly placed on God and Christ. Not human gratification.
It is well worth the read.
