The eleventh of Paul's Epistles is II Timothy. It was written towards the end of Paul's life, in approximately 67 AD.
Before he died, Paul wanted to pass his ministry on to his faithful assistant, who has served him well for many years.
The letter is one of encouragement and it urges Timothy to continue his duties in a faithful manner. Timothy is told to stick to the doctrine he has been taught and to expect to be persecuted for preaching the Gospel; but above all, Timothy is told that he should put all his confidence in the word of God which he is preaching.
II Timothy 3:16-17
"All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: that the man of God may be perfect, throughly furnished unto all good works"
