2 Timothy 3:14-4:4
14 But as for you, continue in what you have learned and have firmly believed, knowing from whom  you learned it 15 and how from childhood you have been acquainted with the sacred writings, which are able to make you wise for salvation through faith in Christ Jesus. 16 All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, 17 that the man of God  may be competent, equipped for every good work.
Preach the Word
4:1 I charge you in the presence of God and of Christ Jesus, who is to judge the living and the dead, and by his appearing and his kingdom: 2 preach the word; be ready in season and out of season; reprove, rebuke, and exhort, with complete patience and teaching. 3 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 passions, 4 and will turn away from listening to the truth and wander off into myths.
