2 Timothy 3:2

Here our apostle reckons up the several sins which would abound in these last days, and make the times perilous: persons professing Christianity shall appear inordinate self-lovers, insatiably covetous, vain-glorious, boasters, proud, despisers of others, blasphemers of God, and Christ, and the Holy Spirit, by denying the prescience and foreknowledge of the former, the divinity and godhead of the latter.

Learn hence, That sins, especially great sins, seldom go single and alone, but commonly generate and beget one another. Thus here, self-love begets covetousness, covetousness pride, and pride blasphemy. Thus men fall from one sin to another, and proceed from one degree of wickedness to another.
