Recently, I have been studying the Book of Job in the Old Testament. I am continually impressed with his perseverance and faith. One thing, in particular, stood out to me. In Chapter 24 it talks about the fact that murderers, adulterers, those who oppress the poor, and wicked often go unpunished. In verse 12 Job points out that though, "Men groan from out of the city, and the soul of the wounded crieth out . . . God layeth not folly to them."
In life those who cheat the system may seem to gain the upperhand. However, in the end everyone will gain that which they have earned (see 2 Corinthians 9:6). As of late, the sporting world has uncovered many cases of athletes using steroids. It seems to me that those athletes who knowingly break the rules by using steroids will gain an advantage over those who do not. However, those who cheat in order to win are never fully satisfied. Not to mention, once they find out that you have been using steroids you could end up in prison.
There are always consequences to our actions whether they come immediately or not. You can never get something for nothing.
