I mean here, however, to accommodate the parable to the purpose of showing in what manner the gospel often addresses itself _to men in different periods of life_, calling one at an early age, and one much later, into the same vineyard of Christ. We are in no danger of erring exactly as the Jews did, by raising objections to Christ's calling the great body of the Gentile nations into his church. We may be in great danger, however, of acting much in the same spirit with the Jews, and if we do so, that spirit is most likely to show itself in our objecting to extend the privileges of the gospel to some poor outcasts or aged sinners among ourselves. First, then, I will put the case of one who is brought to obey the gospel _in the morning of life_, and is one of the youngest of the laborers in our Lord's vineyard. He sets out well, as I will suppose, and goes on well through all the following stages of life; even his most early prayers are not a mere matter of form, but they spring out of a persuasion already rising up in his mind, that he is entirely dependent on God, and needs the help of his Holy Spirit. It pleases God, in answer to his infant prayers, to strengthen this child against his early temptations, so that he does as Christ commands, and not as wicked children may require or expect of him. Such a child as this will also be diligent in learning his lessons, and improving his time; for he will be like the laboring men in the vineyard, spoken of in the parable, and not like the idle ones in the market-place. Now what a vast quantity of good may such a person be the means of doing in the course of a long life on earth. First of all, he is a blessing to his young connections and school-fellows, for he will often reprove vice and irreligion in them, even though it should be much against the modesty of his own natural inclinations. Then he grows up to be a bold witness for God in the face of all the gay and unthinking young men or women among whom he is thrown in early life. Next, he proceeds to do good about the village or town where he is settled. After this, perhaps, he marries, when his wife, and all her connections, and his own offspring also, have the advantage of observing him. They remark his humble, candid, pious, and affectionate spirit, and his diligent and self-denying life, and they profit both by his kind services and his example.
