2 Timothy 3:14-4:5 New Revised Standard Version (NRSV)
14 But as for you, continue in what you have learned and firmly believed, knowing from whom you learned it, 15 and how from childhood you have known the sacred writings that are able to instruct you for salvation through faith in Christ Jesus. 16 All scripture is inspired by God and is[a] useful for teaching, for reproof, for correction, and for training in righteousness, 17 so that everyone who belongs to God may be proficient, equipped for every good work.
4 In the presence of God and of Christ Jesus, who is to judge the living and the dead, and in view of his appearing and his kingdom, I solemnly urge you: 2 proclaim the message; be persistent whether the time is favorable or unfavorable; convince, rebuke, and encourage, with the utmost patience in teaching. 3 For the time is coming when people will not put up with sound doctrine, but having itching ears, they will accumulate for themselves teachers to suit their own desires, 4 and will turn away from listening to the truth and wander away to myths. 5 As for you, always be sober, endure suffering, do the work of an evangelist, carry out your ministry fully.
2 Timothy 4:15-16 New Revised Standard Version (NRSV)
15 You also must beware of him, for he strongly opposed our message.
16 At my first defense no one came to my support, but all deserted me. May it not be counted against them!
