The world of Christians, and their way of life, and their mind, and discourse, and practice, is one thing; and that of the men of this world, another. And the difference between them is very wide. For the children of this world are tossed to and fro by unsettled seasonings, by earthly desires, and a variety of gross imaginations, whereby Satan is continually sifting the whole sinful race of men.

For the word that was spoken to Cain by his Maker, “You shall go mourning and trembling, and be tossed about upon the earth”, is a type and image of all sinners, as to their inward state. For thus is the race of Adam tossed about with the incessant suggestions of fear and dread, and every kind of disturbance, the prince of this world tossing to and fro the soul that is not born of God; and variously disturbing the thoughts of mankind, as corn that is continually shifted about in a sieve; and shaking and ensnaring them all in worldly deceits, and the lusts of the flesh, with fears and troubles.

As from one Adam the whole race of mankind was spread over the earth, so one taint in the affections was derived down into the sinful stock of men; and the prince of malice is sufficiently able to shift them all in restless, and gross, and vain, and troublesome reflections. For as one and the same wind is enough to stir, and shake all plants and seeds whatever, so the prince of wickedness, as an hidden and blustering wind, tosseth to and fro all the race of men upon earth, and, carrying them about with unsettled thoughts, enticing them with the lusts of the world, fills every soul with ignorance, blindness, and oblivion, if it is not born from above. — Homily 4, para 1-3: There is a wide difference between Christians and the men of this world.
