The Apostle Paul sets out the standard in his epistle to Timothy:
"This know also, that in the last days perilous times shall come. For men shall be lovers of their own selves, covetous, boasters, proud, blasphemers, disobedient to parents, unthankful, unholy,without natural affection, trucebreakers, false accusers, incontinent, fierce, despisers of those that are good,traitors, heady, highminded, lovers of pleasures more than lovers of God;Having a form of godliness, but denying the power thereof: from such turn away.
For of this sort are they ... Ever learning, and never able to come to the knowledge of the truth... men of corrupt minds, reprobate concerning the faith. But they shall proceed no further: for their folly shall be manifest unto all men...
But thou hast fully known my doctrine, manner of life, purpose, faith, longsuffering, charity, patience,persecutions, afflictions, which came unto me at Antioch, at Iconium, at Lystra; what persecutions I endured: but out of them all the Lord delivered me. Yea, and all that will live godly in Christ Jesus shall suffer persecution."
