By John Bunyan
Sin is the great block and bar to our happiness, the Procurer of all miseries to man, both here and hereafter. Take away sin, and nothing can hurt us; for death, temporal, spiritual, and eternal, is the wages of it.
Sin, and man for sin, is the object of the wrath of God. How dreadful, therefore, must his case be who continues in sin! For who can bear or grapple with the wrath of God?
No sin against God can be little, because it is against the great God of heaven and earth; but if the sinner can find out a little god, it may be easy to find out little sins.
Sin turns all God's grace into wantonness; it is the dare of his justice, the rape of his mercy, the jeer of his patience, the slight of his power, and the contempt of his love.
Take heed of giving thyself liberty of committing one sin, for that will lead thee to another; till, by an ill custom, it become natural.
To begin a sin, is to lay a foundation for a continuance; this continuance is the mother of custom, and impudence at last the issue.
The death of Christ giveth us the best discovery of ourselves, in what condition we were, in that nothing could help us but that; and the most clear discovery of the dreadful nature of our sins. For if sin be so dreadful a thing as to wring the heart of the Son of God, how shall a poor wretched sinner be able to bear it?
