So suppose we were to look at people who run immoral investment schemes for a living, or, say, a drug dealer who doesn’t use drugs himself, a kingpin. We might see that this person lives a luxurious lifestyle, has fine taste in music and art, appears relaxed and happy most of the time, and apparently has few worries. If we could see into their soul, there might be no major suffering or misery there.
This is why Job cried out “Why do the wicked prosper?” And he persisted in bugging God about it until God answered him.
Now, in the case of sexual sin, it’s worth realizing something, though. In the case of long-term relationships, there is a natural good we are dealing with here. Committed relationships between unmarried couples (straight or gay) have something going for them, because they provide companionship and friendship, which is something we need. I have a hard time believing that these relationships are fueled by nothing other than lust, although lust is what makes them sinful.
In many cases, I think the people who live the most rewarding sinful lives are those who don’t have any real idea that what they’re doing is sinful. I mean, sure, they might know the Church’s rules, but they don’t understand them – or rather, they don’t know God, so the rules have no ooomph to them.
Now the key point here is not that, if these people came to know Christ, their lives would be better. It’s true that they would identify some natural evil, and have the power to avoid the consequences of that evil. But things happen in life.
The key point, rather, is that our lives are not meant for ourselves. Perhaps our lives will be happy and rewarding, but if we focus our lives on being happy and rewarded, this will poison us. Sexuality is intrinsically life-giving. When we live the Truth in our sexual lives, we often find that we suddenly have a bunch of kids running around at our heels; and marriage relationships are no longer about “me” and “you” – they are about the life of the world, and sharing the life-giving love that we have with others.
Happiness and holiness naturally go together, but we don’t live in a state of nature (Eden). In our world, they separate sometimes. And trust me, Satan sets us certain unapologetic sinners in their worldly happiness because he wants to tempt us. But God uses even this temptation to work all things for the good of those who love Him.
Oh, and you could also feel free to start bugging God about it persistently, like Job did. He still answers prayers, even complaints!
