Dearly beloved, I charge thee, before God and Jesus Christ, who shall judge the living and the dead, by His coming, and His kingdom: preach the word: be instant in season, out of season: reprove, entreat, rebuke in all patience and doctrine. For there shall be a time when they will not endure sound doctrine, but according to their own desires they will heap to themselves teachers, having itching ears: and will indeed turn away their hearing from the truth, but will be turned unto fables. But be thou vigilant, labor in all things, do the work of an evangelist, fulfill thy ministry. Be sober. For I am even now ready to be sacrificed: and the time of my dissolution is at hand. I have fought a good fight, I have finished my course, I have kept the faith. As to the rest, there is laid up for me a crown of justice, which the Lord, the just Judge, will render to me in that day: and not only to me, but to them also that love his coming.
From the New Testament, Timothy 4:1-8
