The Bible says that someone who is faithful with a little thing will be faithful with much (Luke 16:9-11). So, if we are honest and we do the right thing when no one is looking, we will be able to be trusted when people are looking.
Stewards are mentioned in the Bible quite a bit actually. The basic message about being a good steward is that God has entrusted us with things down here on earth and it is our responsibility to do something good with them.
"For an overseer, as God's steward, must be above reproach. He must not be arrogant or quick-tempered or a drunkard or violent or greedy for gain, but hospitable, a lover of good, self-controlled, upright, holy, and disciplined. He must hold firm to the trustworthy word as taught, so that he may be able to give instruction in sound doctrine and also to rebuke those who contradict it."
~ Titus 1:7-9
Stewards can only serve one master
“No one can serve two masters. Either he will hate the one and love the other, or he will be devoted to the one and despise the other. You cannot serve both God and Money.” ~ Matthew 6:24
