Some people are trying to do what they were never made for, ambitious beyond their line. This is a grievous evil. In the choice of a calling faith helps a Christian to refuse that which is the most lucrative if it be attended with a questionable morality. If the Christian could have huge purses of that gold which is coined out of the drunkenness, the lust, or the ungodliness of men, he would scorn to put them among his stores. Trades which are injurious to men's minds and hearts are not lawful callings before God.
Dishonest gain is awful loss.
Gold gained by deceit or oppression shall burn into the soul of its owner as the fire of hell. Faith abhors this precept of Mammon, and having God's providence for its inheritance, it scorns the devil's bribe. Choose no calling over which you cannot ask God's blessing, or you will be acting contrary to the law of faith. If you cannot conceive of the Lord Jesus wishing you success in a certain line of trade, do not touch it. If it is not possible to think of your Lord as smiling upon you in your daily calling, then your calling is not fit for a Christian to follow.
