2 Timothy 2:16-17

There is a kind of talk that leads to more ungodliness. This type of talk is worldly and empty chatter. What's interesting is that Paul compares it to gangrene. Gangrene is a disease when large amounts of body tissue dies. This unprofitable talk will spread in such a way. It will be fast, since gangrene spreads at an alarming rate. For some reason, even though this chatter is clearly not good, people find a need to talk about it, and it spreads quickly. Gangrene certainly is deadly, since it is the death of tissue. Consuming your life with chatter like the type Paul refers to here will be deadly for you. As Paul already said, it will produce more ungodliness. There is also no cure to gangrene. Well, by that I mean that back then, there was no cure that would allow you to save the dead tissue. The cure was amputation. Nowadays, there are other cures, such as restoration of the blood flow which may reverse the affects of the gangrene. In the same way, this worldly chatter must be cut off. A note in my bible also translates the word to cancer. Either way, it still remains that this worldly, empty chatter spreads fast, is "bad", and needs to be cut off.
