The Registry in Heaven's Ledger

The customs of the world are no criterion for the Christian. He is not to imitate its sharp practices, its overreaching, its extortion. Every unjust act toward a fellow being is a violation of the golden rule. Every wrong done to the children of God, is done to Christ Himself in the person of His saints. Every attempt to take advantage of the ignorance, weakness, or misfortune of another, is registered as fraud in the ledger of heaven. He who truly fears God, would rather toil day and night, and eat the bread of poverty, than to indulge the passion for gain that oppresses the widow and fatherless or turns the stranger from his right.CS 144.2

The slightest departure from rectitude breaks down the barriers, and prepares the heart to do greater injustice. Just to that extent that a man would gain advantage for himself at the disadvantage of another, will his soul become insensible to the influence of the Spirit of God. Gain obtained at such a cost is a fearful loss.—Prophets and Kings, 651, 652.CS 144.3
