Every Betrayal has a Price
Become poor before the world teaches you poverty by force. not poor in the sense of neglecting what God has given you, refusing necessary things or pretending every comfort is evil, but poor in the number of worldly things you are willing to sin in order to keep. A Christian should be very concerned about anything that can make obedience suddenly negotiable.
The world has plenty to offer. It can offer money, pleasure, sex, admiration, status, entertainment, belonging, beautiful things, an easier life and the approval of people whose opinions seem enormously important while they are standing in front of you. None of these things needs to look particularly wicked on its own, that is what makes attachment so easy, something can be good in its proper place and still become an idol the moment keeping it matters more than keeping yourself from sin.
Christ did not tell the rich young man that possessions were automatically evil, He found the place where the man's obedience stopped. The man wanted eternal life, wanted commandments, wanted righteousness, right until obedience reached what he could not bear to surrender, then he went away sorrowful because he had great possessions. If a pleasure requires sin, become poor in that pleasure. If belonging requires silence when you should speak, become poor in that belonging. If somebody's affection requires disobedience to God, become poor enough to lose the affection. If the world offers approval on the condition that you become ashamed of Christ, let it keep the approval. If comfort requires you to make peace with something you know is wrong, then discomfort is cheaper. There is no created thing valuable enough to make separation from God a reasonable price.
Judas had Christ in front of him and still found something in the world worth exchanging Him for, thirty pieces of silver were enough to put a price on betrayal. He regretted it when the bargain was already made, threw the silver back and died in despair, and that should be warning enough without pretending we know the judgment God alone gave him.
Thirty pieces still spend, they simply come in different forms now. approval, pleasure, money, lust, comfort, status, belonging, whatever somebody wants badly enough that obedience suddenly becomes negotiable, and every Christian should pray that when the world finally discovers his price, it discovers there isn't one.
We have become very good at treating comfort as evidence of blessing and discomfort as evidence that something has gone wrong, but the Gospel gives us no reason to expect Christianity to arrange itself around whatever keeps us comfortable. Christ speaks about the narrow gate, taking up the cross, denying oneself, losing one's life for His sake, leaving things behind and refusing to gain the whole world at the cost of the soul. Somehow we read all of that and still become surprised when obedience eventually asks for something we wanted to keep. The world is temporary and therefore everything it can use to purchase you is temporary too. Money ends, beauty ends, popularity ends, pleasure ends, every crowd eventually disperses and every person whose approval seems indispensable will stand before God themselves. It is an extremely poor bargain to offend God in order to preserve something that was already dying when you chose it.
So become poorer in the things that can buy your conscience. Become harder to bribe with pleasure, harder to frighten with rejection, harder to silence with embarrassment, harder to tempt with comfort. Learn to recognize the moment a good thing begins demanding something evil in exchange for remaining yours, and when that moment comes, let the thing go.
