A false balance is abomination to the Lord: but a just weight is his delight. Proverbs 11:1.
(TDG 343.1)
We need to experience daily a reconversion. If you have taken advantage in your business dealings, which the Lord calls injustice, this must be adjusted before you can be honest and righteous in the sight of God. These things need to be corrected by our people everywhere.... When you take up this work of readjustment and getting right with God, angels of heaven will cooperate with you, giving you discernment to see where you have viewed matters in a wrong light.
(TDG 343.2)
Christ and angels are looking upon your work. They are measuring every action. Let your life represent the meek and lowly Jesus. Strive to do as Christ would do were He in your place. Let there be no disagreement between your measurement of strict integrity and the divine measure. True, pure principles must govern the life of every soul that shall be pronounced just and righteous in the day of God.
(TDG 343.3)
There are many transactions in the business world that the worldling regards as just and honest, but which God condemns. Men lay plans which they regard as right plans, but which do not accord with the true, unselfish principles that Christ has laid down in His Word.... But the approval of the world will never make an unjust action just, and wrong will stand as wrong before the heavenly universe until it is repented of and put away.
(TDG 343.4)
The Lord cannot bless the men who corrupt themselves by unjust business dealings, either with their brethren or with worldlings. And those who do such things lose their spirituality; they grow cold and formal and selfish. They gloss over their past mistakes by theories of their own invention that are opposed to the principles of the Word of God.
(TDG 343.5)
The principle which should characterize every business dealing is clearly laid down by Christ. “All things whatsoever ye would that men should do to you, do ye even so to them: for this is the law and the prophets” (Matthew 7:12)....

The folly, the evil surmising, the uplifting of self, which destroy the fervent zeal of the soul will be put away, and the true believers will be humble of heart, and earnest in their labors for the perishing souls.—Letter 164, November 30, 1909, to the workers in Washington and Mountain View.
