Because spousal love is the most intimate and sacrificial love known to human beings in the natural world, the biblical authors fill the pages of the Bible with its narrative and emotional power. Countless stories of human love, engagement and marriage, anticipation and passion, pregnancy and birth, infidelity and divorce, fill the biblical literature. God and his people are bound by ties of the heart, and they mutually long for the eternal fulfillment of their deepest longings. In fact, the Bible can be described as an undending love story, as the inspired writers use the images and vocabulary of marital love to express the love between God and God's people.
