Run

Running. Something I'm very inclined towards and very good at. Speaking figuratively, of course, not literally. Why? Because it's easier. It's a natural response, and takes much less thought, effort, sweat and tears than the other alternative does. After all, we are engineered to respond to threatening or dangerous things or situations with either fight or flight. The fight-or-flight response is a sequence of internal processes that prepares us for either struggle or escape. It is triggered when we interpret a situation as threatening.
Why is running easier than facing what threatens or scares us? I believe it's because when we run, we can focus all our internal thought processing towards the act of fleeing. Instead of thinking about the problem, we can instead focus on keeping as busy as possible giving us other things to think about and do at all times. We can try to use "happy" things or people or situations or places to give us temporary happiness and help us temporarily forget about the problem or threatening thing. But it's not permanent. And sooner or later, it will come back to haunt you....Because you cannot run forever. You just can't. It's not possible.
Of course, in certain situations the best thing to do is run. 2 Timothy 2:22 clearly emphasizes this point as it commands that we should "Flee the evil desires of youth, and pursue righteousness, faith, love and peace, along with those who call on the Lord out of a pure heart." When we are tempted to sin or to do something that we know is harmful to us or others, we need to run full speed away without looking back. 1 Timothy 6:11 says "But you, man of God, flee from all this, and pursue righteousness, godliness, faith, love, endurance and gentleness."

When, then, is it not the right response to flee? Well, maybe when you're struggling with situations in life that you just can't conquer on your own. So many people, myself very much included, would rather pretend everything's going alright and try their best to ignore the real problem even in their own minds. But somehow at some time that must end, and you must admit to yourself if to no one else that you are absolutely messed up and something must be done. You have to deal with things sooner or later. You can't turn your back forever. No amount of busyness, no number of friends, family or distractions can keep you from the real problems forever. And the sooner you can deal with things, work through them and put them behind you, the sooner you can go on with life and the fuller you can live your life when that has been done.
Months ago I took a Brazilian Jiu Jitsu class once just to try it and see how it compared to the very similar martial art of Judo. In the middle of a fight after I escaped from a pin, I turned my back for a minute just to catch my breath. The instructor immediately yelled at me that "In BJJ, you never turn your back. For in turning your back to your enemy you admit defeat." This is a little different of an idea from how Judo works. In Judo, even in tournament, when the match has been temporarily halted due to a standstill or a partial score or a penalty, you usually have about 5-10 seconds to get up, adjust your uniform, catch your breath, maybe look over at your coach for a few seconds. The ref does not call for the match to continue until both contestants are standing on their respective sides of the mat with their hands up. In watching many matches I've noticed that almost always during one of these brief pauses, the opponent who is down on the scoreboard takes the longest to get back into the "ready" position and stalls as long as is possible without incurring a penalty. I think this is because they feel that their opponent is overpowering them and they have given up a little hope. They know that at some point they have to continue fighting, but they're reluctant because of a small previous defeat. 
In life, this compares to when problems and low points and circumstances have you down. When you get a chance to get up, sometimes it takes a while to get back that courage to continue fighting - because you have started to admit defeat. But after time of not fleeing but instead fighting with everything you've got, it will pay off. You'll be rewarded. When you resist evil, the devil will HAVE to flee from you. And you will be able to stand victorious on the battefield of life - nevermore to flee.
