Suppose you're an employee working for a multi-million dollar business. You've agreed on a set amount of annual income and your job is to do business for the big global company. Now you're a very gifted, clever businessman. And with your talent you can bring millions of dollars of benefit into the company. You become a manager. You have the right to choose what to buy or not to buy, what price to sell or not to sell, which company you'll do business with or which company not to do business with,etc. You become a big target for other people to bribe. With millions of dollars going through your hand everyday, it's very easy and tempting to keep some of the profit to yourself, although you've already got a decent salary. Some people might even beg you to take their bribe so you'd do business with them.
It's hard not to do so. It seems everyone else is doing it in different levels. But then one day the big boss might find out, then I'm not quite sure how happy he will be and if you can still keep your job.
It's the same way with the Kingdom matters. We're all in the kingdom business in different levels. Some are doing "multi-million dollar" business, and some are doing "one to one direct selling" business. We're a channel of God's blessings and His glory. Some people are really gifted in certain ways, and they can witness a mass amount of God's glory manifested through their ministry. Then it becomes a big temptation to keep some of the glory(money)to ourselves. When people pour out their love and adoration to a certain minister rather than God Himself, sometimes for the minister it can really be a kind of "bribe", and it's hard to not to take it.
God, the big boss, knows every detail and every secret. He's not short of talents and gifts, He's not short of salary and blessings, but He wants to find someone that He can trust, someone that will not steal the glory and treasure that belongs to Himself!
