"How is it not absurd to send children out to trades, and to school, and to do all you can for these objects, and yet, not to “bring them up in the chastening and admonition of the Lord”? And for this reason truly we are the first to reap the fruits, because we bring up our children to be insolent and profligate, disobedient, and mere vulgar fellows. Let us not then do this; no, let us listen to this blessed Apostle’s admonition. “Let us bring them up in the chastening and admonition of the Lord.” Let us give them a pattern. Let us make them from the earliest age apply themselves to the reading of the Scriptures. Alas, that so constantly as I repeat this, I am looked upon as trifling! Still, I shall not cease to do my duty."
