“There is such a thing as ‘the deceitfulness of sin’, and it’s very powerful. You start by allowing yourself the apparent luxury of doing something small which you know you shouldn’t but which you think doesn’t matter. When it becomes a habit, you stop thinking it’s wrong at all. If the question is raised, you are ready with rationalizations: everyone does it, this is the way the world is now, you mustn’t be legalistic, no good being a killjoy. This creates a platform for the next move: here’s something else which a while ago you would have shunned as certainly wrong, but it’s quite like the thing you’ve got used to, so maybe… And before too long you’re rationalizing that as well. And once the mind has been deceived, the habit will continue unchecked.”*
I’ve seen this play out many times in so many lives. Wright has summed it up, spot on. I could not have come close to saying it any better.
