Dynamite Fishing

A game warden heard about a local fisherman that was illegally using dynamite to fish at the local lake. So the next day he decided to investigate and mayby catch the fisherman in the act. At about 6 a.m. he arrived at pier dressed as a fisherman himself and noticed a gentleman climbing into a small boat with a tackle box but no fishing pole.

Thinking that this must be the culprit, he asks if he might join the fisherman and come along for the ride. "Sure" says the angler "I could use the company. It'll be nice to have someone to talk to while I'm fishing".

So the game warden climbs aboard and off they row to the middle of the lake. As soon as they reach the middle the fisherman reaches into his tackle box and pulls out a stick of dynamite, lights it and tosses it overboard... CABOOOM!! up float a bunch of dead fish which the fisherman scoops up into the boat.

The game warded pulls out his badge and identifies himself. "I'm the game warden and you're under arrest for fishing with dynamite!"

About this time the old fisherman lights another stick of dynamite, hands it to the game warden and says,
"You gonna talk or fish?"

When it comes to evangelism, are we just talking, or are we fishing?
Are the methods we use for evangelism effective or do they simply cause a lot of collateral damage?
