I am aware that exception is taken to the Sunday-school on the ground that its tendency is to interfere with parental or domestic training. Now I must confess, dearest A., that I cannot see any force whatever in this objection. The true object of the Sunday-school is, not to supersede parental training, but to help it where it exists, or to supply its lack where it does not exist. There are, as you and I well know, hundreds of thousands of dear children who have no parental training at all. Thousands have no parents, and thousands more have parents who are far worse than none. Look at the multitudes that throng the lanes, alleys, and courtyards of our large cities and towns, who seem hardly a degree above mere animal existence--yea, many of them like little incarnate demons. Who can think upon all these precious souls without wishing a hearty God-speed to all _true_ Sunday-school workers, and earnestly longing for more thorough earnestness and energy in that most blessed work? I say "_true_" Sunday-school workers, because I fear that many engage in the work who are not true, not real, not fit. Many, I fear, take it up as a little bit of fashionable religious work, suited to the younger members of religious communities. Many, too, view it as a kind of set-off to a week of self-indulgence, folly, and worldliness. All such persons are an actual hindrance rather than a help to this sacred service. Then again, there are many who sincerely love Christ, and long to serve Him in the Sunday-school, but who are not really fitted for the work. They are deficient in tact, energy, order, and rule. They lack that power to adapt themselves to the children, and to engage their young hearts, which is so essential to the Sunday-school worker. It is a great mistake to suppose that every one who stands idle in the market-place is fit to turn into this particular branch of Christian labor. On the contrary, it needs a person thoroughly fitted of God for it; and if it be asked, "How are we ever to be supplied with suited agents for this branch of evangelistic service?" I reply, Just in the same way as you are to be supplied in any other department--by earnest, persevering, believing prayer. I am most thoroughly persuaded that if Christians were more stirred up by God's Spirit to feel the importance of the Sunday-school--if they could only seize the idea that it is, like the Tract depot and the preaching, part and parcel of that most glorious work to which we are called in these closing days of Christendom's history--if they were more permeated by the idea of the evangelistic nature and object of Sunday-school work, they would be more instant and earnest in prayer, both in the closet and in the public assembly, that the Lord would raise up in our midst a band of earnest, devoted, whole-hearted Sunday-school workers.
