Lessons from evil people

Believe it or not we could learn a lot from evil people. Look at how zealously they serve there god, Satan and look at in comparison how apathetic we serve the true God. Consider the words from Living Zealously by Joel Beeke and James A. La Belle

We should be motivated by people who are violent ways of sin, lest they serve Satan better than we serve God. People of this world are industrious, vigorous, and resolute in the ways of sin, while we are negligent, cold, and inconstant in the service of righteousness. They disregard all reproofs and counsel, they grieve friends and relatives who stand in their way they readily venture into great dangers, they waste their wealth, macerate their bodies, and in the end die martyrs to lust and sin. They are zealous in following the way to hell, while many of us are sluggish on the path to heaven. They break bone and body for hell, while we are afraid to break flesh and skin for glory.

You have to give evil people credit they love what they do and they do it well. What about the Christian?
