Paul to Timothy...

Preach the word, be urgent in season and out of season, convince, rebuke and exhort, be unfailing in patience and in teaching. For the time is coming when people will not endure sound teaching, but having itching ears they will accumulate for themselves teachers to suit their own likings, and will turn away from listening to the truth and wander into myths. As for you, always be steady, endure suffering, do the work of an evangelist, fulfill your ministry.
~2 Timothy 4:2-5
