Proverbs 13:7,11

There is one who makes himself rich, yet has nothing; and one who makes himself poor, yet has great riches.  Wealth gained by dishonesty will be diminished, but he who gathers by labor will increase.

God’s system of gain in this life is always the honest way.  When we work and are reliable, we will be rewarded.  The bible never says we will be rewarded by dishonesty or corruption.  We should never be jealous of those who are making gain through deceit because they usually come to a sad end.  Keep going in this life, and your honest work will be rewarded.
