Have you ever seen a mousetrap? The mouse runs straight for the cheese without noticing there's a hidden trap underneath. Why? Because it only paid attention to what it wanted, not to what could hurt it.
In life, there are 'cheeses' everywhere: things that look great on the outside but hide a price on the inside. A video that seems harmless but keeps you up too late. A friend who seems cool but talks you into doing the wrong thing. The wise one doesn't run for the cheese without looking around first. And you know Who has the best trap-detector of all? Jesus! He said: 'Watch and pray so that you will not fall into temptation.'
