Always make it a goal to keep your conversations cordial. Sometimes that will not be possible. If a principled, charitable expression of your ideas makes someone mad, there’s little you can do about it. Jesus’ teaching made some people furious. Just make sure it’s your ideas that offend and not you, that your beliefs cause the dispute and not your behavior.

I want people to see that Christianity claims to be true in the deep sense, and if it isn't, then it solves nothing at all.

Almost everyone agrees the world is not the way it ought to be. It's called the problem of evil.

According to "matter-ism," matter is all that exists. The only things that are real are physical things in motion governed by natural law. That story starts, "In the beginning were the particles," or, as one famous person put it, "The cosmos is all that is, or ever was, or ever will be." No God. No souls. No Heaven or Hell. No miracles. No transcendent morality. Just molecules in motion following the patterns of natural law. This is the story that most atheists, most "skeptics," most humanists, and most Marxists believe is true.

We want to be on the offensive without being offensive.

People are tempted to think (understandably) that if God were really good He'd never allow any evil in the world at all. But I don't think a perfectly good God would never permit any evil, and neither would others, I wager, if they thought about it. Rather, I think that a good God always prevents suffering and evil unless He has a good reason to allow it. That's the crux.

God existed before He made anything else, and He Himself was never made. God is eternal.
