Every marriage is under attack. Marriage is given to humanity by God as, ultimately, an expression and picture of his love for his people. Satan, the anti-aesthete and anti-tutor, wants to tear this living image down.
There is much to work on in marriage, but it strikes me that there is a single key that unlocks the door to health: humble repentance. As sinners living together under the same roof, husband and wife will annoy one another, hurt one another, and fail to edify one another as they should. Sin and its baggage are not only possible, but inevitable for even the godliest couple. If we pretend otherwise, if we act as if we can bat 1.000 all the time, if we plaster smiles on our faces and project the image of perfection, then we lie to ourselves and to others.
Most significantly, we lie to God, who knows the depth of our fallenness, and who is justly offended by our sin.
The single most important key to a strong marriage, it seems to me, is humble repentance. Sin is the fundamental problem of our marriages; humble repentance is the fundamental solution. What does this mean? It means that husbands and wives must train themselves to be experts in the art of saying “I was wrong. I hurt you. I get that. I am so sorry.” What a simple collection of words, but what a punch they pack.
It is surprisingly easy for even loving couples to get out of this habit. You hurt your spouse, and she lets you know as she should, but you don’t apologize. You skate over it. We all come to a moment on a regular basis when we arrive at a fork in the road: we can take one path and evade meaningful confession, or we can swallow our pride and take the route of humility. Whether you’re married or not, you know what I’m talking about. Taking the first path guarantees that things will get harder, that sin will calcify. Taking the second brings light into the marriage; the pressure releases, and it’s as if someone opened the blinds in a gloomy house. The light of the gospel shines again.
