Back in ancient times, one of the most effective defences a city could have was whopping great walls around its perimeters. With walls, a city had much less chance of being taken over. Walls provided a first line of defence. There'd be trained watchmen stationed on top of them, and the minute they caught sight of an incoming enemy, they'd raise the alarm for the guards to rush to the gates and fight back.
'Whoever has no rule over his own spirit is like a city broken down, without walls' (Proverbs 25:28 NKJ). So, when we don't bother with self-control, we leave ourselves wide open to an incoming enemy we wouldn't want to settle down in the city of our soul. The minute we allow ourselves to do just-that-one-thing- we-know-we-shouldn't, we start to let our walls down. And once those walls are down, it becomes ever-easier to let one more thing slide. And then another thing. And another. And...
You get the idea. The bottom line is this: letting something slide, even one tiny little thing, doesn't work. We may not feel the impact immediately, but even the smallest thing changes the way we think about what's right. It draws us a step further away from God. And each step further away makes the next one a little easier to take.
So what now? Ask the Holy Spirit for His help in growing self-control. And then ask for His help in maintaining it and keeping your walls intact.
