For many years scientists and philosophers have pondered why we need sleep besides to not be sleepy. Of course we all intuitively know how important sleep is to our bodies, relationships, and walk with God. But as neuroscientists are learning more about the brain, they are discovering many positive brain benefits from sleep. This list below includes some of those benefits.
- Sleep improves mood. And people catch a leaders’s mood. It’s called emotional contagion. If we regularly don’t get enough sleep, it can make us grumpy and negative. If we carry a bad mood to church, it rubs off on others. The reverse holds true as well. A good mood rubs off on others.
- Sleep enhances memory. When we sleep our brain turns short term memory into long-term memory. It’s called memory consolidation. Without adequate sleep, consolidation suffers.
- Sleep improves decision making. When we don’t get adequate sleep we can become more rigid in our thinking and less adaptable. Rigid thinking impairs good decision making.
- Sleep improves creativity. Studies have shown that sleep facilitates insight because the brain is still active while we sleep. Among other things, it uncovers novel connections between seemingly disparate ideas. The old adage “sleep on it” really is true.
- Sleep improves our ability to pay attention. Great leaders listen well to others and have the ability to maintain attention to important tasks. Lack of sleep degrades our brain’s ability to pay attention.
- Sleep clears out the brain’s ‘trash’ to make it more effective. Neuroscientists have discovered that during waking hours toxins collect in our brains while sleep literally cleans them out.
If you regularly don’t get enough sleep, your leadership may be suffering. The writer of Ecclesiates writes, The sleep of a laborer is sweet. (Ecc 5.12, NIV)

For years doctors have warned us that prolonged stress can hurt our bodies such as causing high blood pressure and stomach problems. But as neuroscientists learn more about our brains, they’re discovering that stress can diminish brain functioning which in turn shows up in subtle ways in our bodies. Take the quick self evaluation below and ask yourself if any of these are true of you.
- I seem a bit more forgetful. Prolonged stress actually diminishes our memory because it can shrink a key memory center called the hippocampus.
- I don’t feel as motivated as I usually do. A key brain chemical (neurotransmitter) called norepinephrine helps us stay alert and focused in the right amounts. However prolonged stress decreases it which can lessen our motivation.
- Things I once enjoyed seem less enjoyable now. Dopamine, the pleasure neurotransmitter, activates our pleasure centers so that things such as finishing a task and eating actually feel good. Stress dampens this important chemical which can result in less pleasure from what we normally enjoy.
- I feel more ‘blue’ than I usually do. Again, another neurotransmitter is at play here, serotonin, which regulates mood. As you might expect, stress dampens its availability in the brain. Most depression medicines aim to regulate serotonin in the brain.
So prolonged stress clearly impacts our brains which negatively affects our daily lives. It behooves us to wisely manage it. In a future post I’ll suggest some simple ways to deal with stress.

My first degree, industrial engineering, taught me to think systematically which has in turn benefited my pastoral leadership. Since then I’ve read many books on church planning and been certified through Ministry Advantage and Auxano, two strategic planning/pastoral coaching organizations. I’ve also led two churches where I’ve served through a year-long strategic planning process. So, I’m well-versed and trained in the church visioning/planning process. Yet, of all the books I’ve read on strategic planning, Will Mancini’s book, Church Unique is the best. In his chapter called “Lost on the Way to Your Own DNA,” he lists subtle thinking patterns that can hinder church growth. He calls these patterns ‘thinkholes.’ I’ve listed them here with brief definitions.
- The ministry treadmill: busyness eliminates time for reflection.
- leads to just adding more programs
- The competency trap: presumption that past methods will continue to work decreases appetite for learning.
- leads to just working harder
- The needs based slippery slope: consumerism removes the need for discernment.
- leads to trying to make people happy
- The cultural whirlpool 1: BuzzChurch-innovation short circuits self-awareness.
- leads to just trying to be cutting edge
- The cultural whirlpool 2: StuckChurch-change outpaces the discipline for learning.
- leads to glorifying the past
- The conference maze: success increases the temptation to copycat.
- leads to simply modeling best practices
- The denominational rut: resources disregard local uniqueness.
- leads to just protecting theology
At times I’ve been caught up in these thinkholes. How about you?
What other thinkholes would you add to this list?
Recently I posted a blog titled “Top 10 Reasons People Don’t Tithe.” I took it from a recent sermon I preached at my church, West Park Church in London, Ontario. I didn’t expect it to go viral and certainly didn’t anticipate the controversy it generated. Here’s the reader interaction stats on it (from my website, Google analytics, and Churchleaders.com that posted it twice) and what I learned.
- Re-tweets: almost 100
- Facebook shares: 1124
- Comments on Churchleaders.com: 253 at last count
- Facebook ‘Likes’ on Churchleaders.com: 3,400 at last count
- Pageviews on my website: 12,000 plus at last count
To put this into context, I’m not a big league blogger like some you probably read. I post twice a week primarily on church leadership. I average around 7,000 unique page views per month and I have an email list of followers of around 2,400. So, I don’t rank very high in the blogosphere.
So, when I began to see these trends, I knew something was up. Here are the insights I’ve learned from this post.
- The concept of tithing remains very controversial. From my 35 years in ministry I knew people had differing views. However, I never knew those views would create such emotion.
- Some people get incendiary when pastors talk about money. I was quite surprised at some of the emotion laden darts commenters threw out at pastors. The comments revealed lots of angst people carry toward pastors and money.
- Some people can disagree agreeably. Although I didn’t read all 250 plus comments, I read enough to see that several thoughtfully shared their differing viewpoints. They made good points without SHOUTING!
- Social media is reinforcing unhealthy ‘filterless’ communication.
I was shocked at how mean some of the comments were. In contrast to those who agreeably disagreed with me, some commenters threw multiple verbal grenades. In our social networking world when we don’t have to talk to a real live person standing a few feet away from us, we tend to thoughtlessly speak our mind with no love to temper us. Social networking is giving people a forum to say what they want with no filters. This is not a healthy trend.
- I support everyone’s right to dissent, even if they lack filters. Although filterless communication is not the healthiest kind, I still support everyone’s right to dissent. Unfortunately, especially in today’s politically correct world, those of us who take biblical stances on issues (i.e., on biblical marriage) are being marginalized more and more.
Why do you think this post generated so much controversy?
Leadership demands our time, energy, and often our financial resources. Hopefully the projects and people we invest ourselves in are worthwhile and fulfilling. Often we invest so much of ‘us’ into a project that we can’t imagine not finishing the project. When we’ve already invested considerable time and energy into something, stopping it may seem foolish. Unfortunately, we seldom ask ourselves if we really should continue investing in a project. A subtle mental trap comes into play called the sunk cost bias. Sunk cost bias simply means that because you’ve invested so much emotionally into a project, you feel that by quitting you’d waste what you’ve already invested and be a failure, even though you actually should cut your losses and re-direct your efforts. Consider these 5 signs that the sunk cost bias might be driving some of your leadership decisions.
- You have a nagging sense that you probably need to go another direction. Perhaps you’ve gotten new information or the landscape has changed and you have begun to doubt if you should continue in the current direction. And, you can’t seem to shake those doubts.
- You want things to change in your ministry or church, but you keep doing the same things over and over again, expecting to get different results. Einstein defined this as insanity.
- You know you should stop the project but fear having to explain yourself to others.
- You’ve poured so much into this project that that your emotional attachment has made you lose sight of your greater goals and vision.
- The project drains your energy rather than boosting it.
If any of these 5 signs are true of you, the sunk cost bias may be distorting your judgment. Consider taking these steps to evaluate whether or not you should cut your losses on some project and go a different direction.
- Talk to someone about your struggle who will maintain their objectivity and be honest with you.
- Play out the scenario if you did stop. What benefits would you gain? What new costs would you incur? What more productive project could you then invest your time and energy into?
- Were you to stop, who would you need to explain your decision to? How would you explain your decision? Might they actually respect you for making such a decision?
- Re-visit your values. Does the project align with your personal and ministry values and God’s call on your life?
How have you seen the sunk cost bias play out in your life or other people’s lives?
