Greg Koukl quotes:

If Darwinism is true, then there is no purpose or meaning to life, there is no morality, there's no qualitative difference between humans and animals, there's no life after death, and there's no purpose to human history. Now, are you trying to tell me that it doesn't really matter if people believe we evolved or not?

Some say Christianity is just a crutch. But let's turn the question on its edge for a moment. Is atheism an emotional crutch, wishful thinking? The ax cuts both ways. Perhaps atheists are rejecting God because they've had a bad relationship with their father. Instead of inventing God, have atheists invented non-God? Have they invented atheism to escape some of the frightening implications of God's existence? Think about it.

Cursed is everyone who hangs on a tree.

If the unborn is a human person, no justification for abortion is adequate.

Whenever someone tries to deny the truth, ultimately, reality betrays him.

So let's set the record straight. Faith is not the opposite of reason. The opposite of faith is unbelief. And reason is not the opposite of faith. The opposite of reason is irrationality. Do some Christians have irrational faith? Sure. Do some skeptics have unreasonable unbelief? You bet. It works both ways.

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.

An alternate explanation is not a refutation.

There is no neutral ground when it comes to the tolerance question. Everybody has a point of view she thinks is right, and everybody passes judgment at some point or another. The Christian gets pigeonholed as the judgmental one, but everyone else is judging, too, even people who consider themselves relativists.

We want to be on the offensive without being offensive.

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