“Reflecting on forty years of matrimony, John Piper exalts the biblical meaning of marriage over its emotion, exhorting couples to keep their covenant for all the best reasons. Even in the days when people commonly stayed married “til death do us part,” there has never been a generation whose view of marriage was high enough, says Pastor John Piper. That is all the more true in our casual times. This Momentary Marriage unpacks the biblical vision, its unexpected contours, and its weighty implications for married, single, divorced, and remarried alike.

This unique book introduces a biblical and practical approach to those realities that is rooted in God’s faithfulness and Scripture’s teaching on sin and grace. “Spouses need to be reconciled to each other and to God on a daily basis,” Tripp declares. “Since we’re always sinners married to sinners, reconciliation isn’t just the right response in moments of failure. It must be the lifestyle of any healthy marriage.”

What Did You Expect? presents six practical commitments that give shape and momentum to such a lifestyle. These commitments, which include honestly facing sin, weakness, and failure; willingness to change; and embodying Christ’s love, will equip couples to develop a thriving, grace-based marriage in all circumstances and seasons of their relationship.
