Every morning I drive across the same set of rail road tracks. They're nothing special. Just typical railroad tracks on top of a mini hill and a set of lights and arms that stretch across just to stop traffic should a train be oncoming.
What I find interesting though, is that every time I go over these tracks, people either a) go over the tracks without paying attention or b) look for a train as they pass over the tracks.
The observation: People depend on the flashing lights and bells to tell them that the train is on it's way. What if a train was coming and the power was out? Or the lights simply weren't working? There are houses that line both sides of the track, so people wouldn't see the train until it was too late. They cross the track...SMASH!
We do this spiritually all the time. We get involved in something and think nothing of it. We say to ourselves that if something is wrong with this, God is going to send me flashing lights and bells to warn me. But we head straight on towards those tracks without looking for any danger. By the time we hit the track, we're so far gone we don't see the train coming and soon after that, there is a train wreck.
"Submit yourselves, then, to God. Resist the devil, and he wil flee from you. Come near to God and he will come near to you. Wash your hands, you sinners, and purify your hearts, you double-minded. Grieve, mourn and wail. Change your laughter to mourning and your joy to gloom. Humble yourselves before the Lord, and he will life you up." - James 4:7-10
The more often we come to God grieving because of our own brokenness, the better off we are in seeing that train coming before it's too late. We can't always depend on those flashing lights to get our attention. We have to constantly be on guard to resist the enemy.
