“Idleness is the great corrupter of youth, and the bane and dishonor of middle age. He who, in the prime of life, finds time to hang heavy on his hands, may with much reason suspect that he has not consulted the duties which the consideration of his age imposed upon him; assuredly he has not consulted his happiness.”

Context: A father would do well, as his son grows up, and is capable of it, to talk familiarly with him; nay, ask his advice, and consult with him about those things wherein he has any knowledge or understanding. By this, the father will gain two things, both of great moment. The sooner you treat him as a man, the sooner he will begin to be one; and if you admit him into serious discourses sometimes with you, you will insensibly raise his mind above the usual amusements of youth, and those trifling occupations which it is commonly wasted in. For it is easy to observe, that many young men continue longer in thought and conversation of school-boys than otherwise they would, because their parents keep them at that distance, and in that low rank, by all their carriage to them.

Jonathan Edwards, A Treatise Concerning Religious Affections (1746), PART II : Showing What Are No Certain Signs That Religious Affections Are Truly Gracious, Or That They Are Not, Ch. 11: Nothing can be certainly known of the nature of Religious Affections, that they much dispose persons with their mouths to praise and glorify God. <!-- (1831 edition), p. 194, also in Complete Christian Classics (1999), Vol. 1, p. 365 -->
Context: !-- He who has a false hope, has not that sight of his own corruptions which the saint has. A true Christian has ten times more to do with his heart and its corruptions, than a hypocrite: and the sins of his heart and practice, appear to him in their blackness; they look dreadful; and it often appears a very mysterious thing, that any grace can be consistent with such corruption, or should be in such a heart. But a false hope hides corruption, covers it all over, and the hypocrite looks clean and bright in his own eyes.
--> There are two sorts of hypocrites: one that are deceived with their outward morality and external religion; many of which are professed Arminians, in the doctrine of justification: and the other, are those that are deceived with false discoveries and elevations; which often cry down works, and men's own righteousness, and talk much of free grace; but at the same time make a righteousness of their discoveries, and of their humiliation, and exalt themselves to heaven with them. These two kinds of hypocrites, Mr. Shepard, in his Exposition of the Parable of the Ten Virgins, distinguishes by the names of legal and evangelical hypocrites; and often speaks of the latter as the worst. And it is evident that the latter are commonly by far the most confident in their hope, and with the most difficulty brought off from it: I have scarcely known the instance of such a one, in my life, that has been undeceived.
