O Timothy, guard what is laid up in trust with you, turning away from the empty speeches that violate what is holy and from the contradictions of the falsely called “knowledge.” 21 For making a show of such [knowledge] some have deviated from the faith.
2 Timothy 3:1-13
1 But know this, that in the last days critical times hard to deal with will be here. 2 For men will be lovers of themselves, lovers of money, self-assuming, haughty, blasphemers, disobedient to parents, unthankful, disloyal, 3 having no natural affection, not open to any agreement, slanderers, without self-control, fierce, without love of goodness, 4 betrayers, headstrong, puffed up [with pride], lovers of pleasures rather than lovers of God, 5 having a form of godly devotion but proving false to its power; and from these turn away. 6 For from these arise those men who slyly work their way into households and lead as their captives weak women loaded down with sins, led by various desires, 7 always learning and yet never able to come to an accurate knowledge of truth.
8 Now in the way that Jan´nes and Jam´bres resisted Moses, so these also go on resisting the truth, men completely corrupted in mind, disapproved as regards the faith. 9 Nevertheless, they will make no further progress, for their madness will be very plain to all, even as the [madness] of those [two men] became. 10 But you have closely followed my teaching, my course of life, my purpose, my faith, my long-suffering, my love, my endurance, 11 my persecutions, my sufferings, the sort of things that happened to me in Antioch, in I·co´ni·um, in Lys´tra, the sort of persecutions I have borne; and yet out of them all the Lord delivered me. 12 In fact, all those desiring to live with godly devotion in association with Christ Jesus will also be persecuted. 13 But wicked men and impostors will advance from bad to worse, misleading and being misled.
16 All Scripture is inspired of God and beneficial for teaching, for reproving, for setting things straight, for disciplining in righteousness, 17 that the man of God may be fully competent, completely equipped for every good work.
