A freight train rolling downhill does not stop because the engineer decides to stop thinking about moving forward. It does not halt because someone on board feels really bad about where the train is headed. It does not slow down because of good intentions or sincere regret. A train rolling downhill has momentum, and momentum is a physical force that requires a physical intervention. You cannot think a train into stopping. You have to actively arrest it with brakes, friction, and opposing force. Sin works the same way.

Yesterday we introduced ARREST, the first step of the Watchman’s Protocol. We talked about stopping the momentum before a rogue thought gains entry to your mind. Today we need to understand why stopping matters so much. It matters because sin is not a static condition you can reason with; it is kinetic energy in motion. Once it starts rolling, it picks up speed. The longer you let it roll, the harder it becomes to stop. The impulse to send the cutting remark, the urge to click the link you know you should not click, the temptation to exaggerate the story to make yourself look better, these are not passive thoughts sitting still waiting for you to analyze them. They are freight trains already moving, and every second you delay is another second they gain momentum.

Most of us treat sin like a debate we can win with better arguments. We stand on the tracks trying to persuade the train to stop. We tell ourselves, “I should not do this. This is wrong. I know better.” And then we do it anyway, confused about why our convictions did not translate into different behavior. The answer is simple: you cannot think your way out of a physiological hijack. Sin has kinetic energy. It floods your body with adrenaline, tightens your chest, heats your face, speeds your typing. By the time you are trying to think clearly, your body is already three steps into the sin cycle. The train is rolling. Reasoning with it now is like trying to negotiate with gravity.

Here is what this looks like in practice. You wake up, grab your phone, open the app you promised yourself yesterday you would delete, and twenty minutes later you are staring at content you swore you would never look at again. How did that happen? It happened because you let the train roll. The first movement was automatic: wake up, grab phone. The second movement gained speed: unlock screen, tap app. By the third movement, the momentum was unstoppable. You were not making decisions anymore; you were riding momentum. The solution is not trying harder tomorrow morning with more willpower. The solution is derailing the train tonight by deleting the app, moving the phone to another room, replacing the morning ritual with something that points in a different direction. Physical momentum requires physical disruption.

This is why ARREST is the first step of the protocol, not the third or fourth. If you do not stop the momentum at the perimeter, you will not have the clarity to AUDIT the impulse, ALIGN to truth, or ACT with wisdom. You will just react. You will say the thing you wish you had not said. You will click the link. You will send the email. And afterward, you will wonder why your convictions did not protect you. They did not protect you because convictions are not brake systems. Convictions tell you where you want to go; they do not stop the train when it is already moving in the wrong direction. That requires intervention. That requires you to physically remove your hands from the keyboard, close the laptop, step outside, splash water on your face, do ten push-ups, anything that disrupts the kinetic energy before it completes its arc.

Tomorrow we will talk about becoming the Sheriff of your own mind, about taking authority over the thoughts trying to gain entry. But today, the work is simpler: recognize that sin has momentum, and momentum does not stop on its own. When you feel the heat rising, when your fingers start typing faster, when the urgency to act right now floods your chest, that is not a debate starting. That is a train rolling. You do not negotiate with it. You do not try to think your way out of it. You arrest it. You physically disrupt the motion before it picks up enough speed to derail everything you have built. The train is already moving. Stop it now, or ride it to the bottom.
