We've seen in the past two studies that it is very important to have your life shaped by the right examples. The power of a great example is the first of two forces designed to make ordinary people, young in experience, just like Timothy, strong forces for the extension of God's mighty kingdom in this dark world.
The constant tendency is to carelessly allow your life to be molded by bad examples rather than good. That's why Paul reminds Timothy that the bad will only get worse in this fallen world. Bad people are essentially weak people. They have reached their state by choosing the path of least resistance. The wrong crowd will always tempt you to think you are out to lunch if you don't walk within their plans. There is always tremendous pressure to conform to the wrong spiritual shape in this world. Paul says Timothy, and all who want to be godly, must constantly resist that pressure.
