2 Timothy 3:1 NIV

1 John 2:18 niv
Dear children, this is the last hour; and as you have heard that the antichrist is coming, even now many antichrists have come. This is how we know it is the last hour.

1 Timothy 4:1-3 niv
The Spirit clearly says that in later times some will abandon the faith and follow deceiving spirits and things taught by demons. Such teachings come through hypocritical liars, whose consciences have been seared as with a hot iron. They forbid people to marry and order them to abstain from certain foods, which God created to be received with thanksgiving by those who believe and who know the truth.

2 Peter 3:3 niv
Above all, you must understand that in the last days scoffers will come, scoffing and following their own evil desires.

2 Timothy 4:3 niv
For the time will come when people will not put up with sound doctrine. Instead, to suit their own desires, they will gather around them a great number of teachers to say what their itching ears want to hear.
