Fight the good fight
Preach the word; be instant in season, out of season; reprove, rebuke, exhort with all long suffering and doctrine.
For the time will come when they will not endure sound doctrine; but after their own lusts shall they heap to themselves teachers, having itching ears;
And they shall turn away their ears from the truth, and shall be turned unto fables.
But watch thou in all things, endure afflictions, do the work of an evangelist, make full proof of thy ministry.
For I am now ready to be offered, and the time of my departure is at hand.
I have fought a good fight, I have finished my course, I have kept the faith:
Henceforth there is laid up for me a crown of righteousness, which the Lord, the righteous judge, shall give me at that day: and not to me only, but unto all them also that love his appearing.
2 Timothy 4:2-8 KJV
