If the Christian doesn't get reality right, he loses effectiveness in this life. If the non-Christian doesn't get reality right, he loses much in this life, and everything and the next one. As Jesus put it, "What does it profit a man if he gains the whole world and loses his soul?"

Our value is built into us, and nothing and no one can take it away.

Our innate, built-in human value is the reason we have binding duties or obligations towards each other that we don't have towards any other kind of thing. It's also the reason we have unalienable human rights. If man's God-given, special value falls, then unalienable human rights fall, too.

God created man to share friendship with Him and share in His happiness.

If the Story is not accurate to reality, it's not any kind of truth at all. So it can never be 'my truth' or 'your truth,' even though we may believe it. It can only be our delusion or our mistake or our error, but it can never be our 'truth.'

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.

You may be a fantastic person, and you may have some wonderful religious views that might even turn out to be true, but the religion you'd be following would not be Christianity.
