2 Timothy 2:15-17

2:15 Make every effort to present yourself before God as a proven worker who does not need to be ashamed, teaching the message of truth accurately. 2:16 But avoid profane chatter, because those occupied with it will stray further and further into ungodliness, 2:17 and their message will spread its infection like gangrene. Hymenaeus and Philetus are in this group.
