British evangelist Rico Tice says, "Loving people means warning people." He illustrates with the following personal story:

I was once in Australia visiting a friend. He took me to a beach on Botany Bay, so I decided I had to go for a swim. I was just taking off my shirt when he said: "What are you doing." I said: "I'm going for a swim." He said: "What about those signs?" And he pointed me to some signs I'd not really noticed— Danger: Sharks! With all the confidence of an Englishman abroad, I said: "Don't be ridiculous— I'll be fine." He said: "Listen mate, 200 Australians have died in shark attacks— you've got to decide whether those shark signs are there to save you or to ruin your fun. You're of age—you decide." I decided not to go for a swim.

[Many of the words about hell found in the Bible] are all straight from Jesus' lips. And they're a loving warning to us. The reason Jesus talked about hell is because he does not want people to go there. The reason Jesus died was so that people wouldn't have to go there. The only way to get to hell is to trample over the cross of Jesus. That is a great motivator for our evangelism.
