Caught in a Crush :

“These experiences hint at the type of closeness we hope for in the world to come, where we will be known, even as we are fully known, as we experience an intimacy with God and all redeemed creatures that we can only faintly imagine now. The aches we experience remind us that we still live here, in our shadowy bodies and broken world. But our longings can also remind us that we are moving toward something more. On the most fundamental level, our aches point homeward. As Frederick Buechner wrote, ‘Beneath the longing to possess and to be possessed by the beauty of another sexually %u2014 to know, in the Biblical idiom %u2014 there lies a longing, closer to the heart of the matter still, which is the longing to be at last where we finally belong…. When I think of all the beautiful ones whom I have seen for maybe no more than a passing moment and have helplessly, overwhelmingly desired, I wonder if at the innermost heart of my desiring, there wasn’t, of all things, homesickness.’”

This is a great article on dealing with the longings we all have for Heaven which are misplaced onto others. I disagree with the sinful spouses definition. It is more areas which the grace of God has not been realized, the unmet needs of childhood, and the temptation of the Evil one.
