We rationalize ‘sleeping around’ as freedom because we think our body needs this sort of reckless venue for pleasure. But after a while, that’s sort of shallow and superficial. It’s really missing out on the Big Picture. A committed, covenantal promise to be forever faithful to a husband or wife in a stable family unit of sacrifice through every season always leads to the best sex ever. That’s an ocean-deep foundation of nourishing goodness that makes anything else pale in comparison. God wants to give you the real thing, not a cheap imitation. It’s like holding a candle to the sun.

Being free does not mean that you maintain an image to sell yourself to the nearest sexual object to satisfy your flesh for a minute, or to play the paranoid game of ‘I better keep this up or he/she will leave me.’ Being really free in a marriage means you have an unfailing love that is stronger than every hardship in life, stronger than your feelings, and big enough to grow you into God’s glorious vision.
