John Wesley on Matthew 18:7

Wo to the world because of offences - That is, unspeakable misery will be in the world through them; for it must needs be that offences come - Such is the nature of things, and such the weakness, folly, and wickedness of mankind, that it cannot be but they will come; but wo to that man - That is, miserable is that man, by whom the offence cometh. Offences are, all things whereby any one is turned out of, or hindered in the way of God.
