How great the difference between acting according to the word of God and according to our own natural desires, or the customs of the world, will be plain, I trust, by the following case: Suppose I were engaged in some useful trade. Suppose I had the certain human prospect that within the next three months my labor would bring me in nothing, for certain reasons connected with the state of mercantile affairs. As a man of the world I should say, I shall not work at all, because my labor will not be paid; but as a Christian, who desires to act according to God's holy word, I ought to say, My trade is useful to society, and I will work, notwithstanding all human prospects, because the Lord Jesus has commanded me to labor; from him, and not from my trade, I expect my wages. In addition to this, the Christian ought also to say, Idleness is a dreadful snare of the devil; he has especial opportunity to get an advantage over the children of God when they are unoccupied; and, therefore, I will work though I have no human prospect of obtaining payment for my labor, but shall get only the cost price of the material, and shall have to give my work for nothing. Moreover, the Christian ought to say, Though according to _human_ probability I shall have to labor for nothing during the next three months, yet I will work, because the Lord may speedily alter the state of things, contrary to all human expectation; but whether he be pleased to do so or not, I labor because I am the Lord's, bought by his precious blood, and he commands me to labor. But there are motives still lower than to be engaged in our earthly calling merely that we may earn the means of obtaining the necessaries of life, why even Christians, true children of God, may be engaged in their calling, such as, to obtain a certain sum of money, and then to retire from business and to live upon the interest; or to provide something for old age; or to obtain a certain amount of property, without intending to give up business. If it be unscriptural to be engaged in our calling merely even for the sake of earning the means for procuring the necessaries of life for ourselves and family, how much more unbecoming that a child of God should be engaged in his calling for the sake of any of the last-mentioned reasons.
