Reality has a way of injuring people who don't take it seriously. If you don't believe in gravity, for example, and then step off a tall building, you won't just float away.

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.

Every worldview has its ambiguities - debatable elements that people simply will not see to eye on. There's nothing wrong with that as long as the disagreement is principled and dignified. I actually think that arguments - as opposed to quarrels - are good things because they're the best way to figure out what's true. Share your reasons, listen carefully to each other, be nice, and may the best idea win.

Wisdom is an artful method—a skillful, tactical, fair, and diplomatic use of knowledge.

Cursed is everyone who hangs on a tree.

Something good made something bad possible (though not inevitable). Humans, however, didn't use their freedom well. Instead of using it to honor God in friendship, they used it to rebel.

We want to be on the offensive without being offensive.
