There was a time when I wondered how bad people made so much money. I thought that the Bible commanded us to be diligent and so rich people should be good people. How interesting it was when I discovered that good work ethic was used by the greedy as well as the good. Their greed drives them to recognize the self-evident truths of work ethic. So, Bible believing folks are motivated by Biblical principle to be diligent. Covetous people are motivated by their greed to be diligent as well.
There are very different results, however. Covetous people combine deception with diligence to create wealth. The deception can create temporary relationships intended for gain and perhaps for emotional/physical benefits. However, deception destroys trust. Deception is eventually discovered and the relationships are ruined. These are replaced by more deceptive relationships. The same results follow. Great wealth can be accumulated. However, great relationships based upon deception cannot be created. Since accomplishment is based upon relationship, eventually accomplishment is blunted. Wealth may or may not endure.
Bible believing people, who are motivated to diligence by love for truth as well as accomplishment, build relationships based upon reliable trust. Because they deny themselves the advantages of deception, some wealth is foregone. However, the wealth gained brings less sorrow that would result from deception. Both the wealth and the relationships tend to endure.
We have left Someone out of the topic, so far: God. When Bible believing folks return a portion of the wealth gained from honest diligence to the Creator of all things, they are demonstrating a humility which God's Word, the Bible, says that He honors. When a person is honored by God, he or she is honored indeed.
Christ said, "No man can serve two masters....you cannot serve God and mammon." (Luke 16:13, KJV) "But seek ye first the kingdom of God and His righteousness; and all these things shall be added unto you." (Matt. 6:33) As one pastor said, you may not be able to take it with you. But, you can send it on ahead. This option is not available to those motivated by greed.
