Read Acts 23 today.

Acts 23:12-15 NLT[12] The next morning a group of Jews got together and bound themselves with an oath not to eat or drink until they had killed Paul. [13] There were more than forty of them in the conspiracy. [14] They went to the leading priests and elders and told them, “We have bound ourselves with an oath to eat nothing until we have killed Paul. [15] So you and the high council should ask the commander to bring Paul back to the council again. Pretend you want to examine his case more fully. We will kill him on the way.”
I think reading these four verses almost always make me pause to think for a few minutes. Even though I am aware of our sinful nature and the path down which that nature leads us, this kind of thinking still surprises me. It reminds me that when we have great passion about something, regardless of what it may be, we may be tempted to use extraordinary (and often sinful) means to accomplish the end we seek.
We see this in sports where players and teams are willing to ‘play dirty’ in order to gain a competitive advantage. We see it in school where students are willing to cheat in order to get a better grade. We see it in jobs where people are willing to take credit for the work of other people in order to get ahead. If we see it in so many situations around us, we should probably be watching for it to show up in our own lives.
What are the areas of your life where you have great passion and zeal? Have you ever been tempted to compromise your integrity or morals to get ahead in those areas? What do you need to do in order to make the means to the end as important as the end itself?
