The Bible says all men are without excuse. Even those who are given no good reason to believe and many persuasive reasons to disbelieve have no excuse, because the ultimate reason they do not believe is that they have deliberately rejected God's Holy Spirit.

But the argument is still unsound, because the first premise is false: there are other unmentioned alternatives, for example, that Jesus as described in the gospels is a legendary figure, so that the trilemma is false as it stands.

Part of the broader task of Christian scholarship is to help create and sustain a cultural milieu in which the gospel can be heard as an intellectually viable option for thinking men and women.

Scepticism, ironically, draws its life's blood from claims to have a good deal of knowledge. For example, your friends claim to know, 'Since every possible option has not been explored, nothing can be said for certain.' That statement is itself a claim to knowledge!

Therefore, when a person refuses to come to Christ it is never just because of lack of evidence or because of intellectual difficulties: at root, he refuses to come because he willingly ignores and rejects the drawing of God's Spirit on his heart. No one in the final analysis really fails to become a Christian because of lack of arguments; he fails to become a Christian because he loves darkness rather than light and wants nothing to do with God.

Reason is a tool to help us better understand and defend our faith; as Anselm put it, ours is a faith that seeks understanding.

So whom does God wrong in commanding the destruction of the Canaanites? Not the Canaanite adults, for they were corrupt and deserving of judgment. Not the children, for they inherit eternal life. So who is wronged? Ironically, I think the most difficult part of this whole debate is the apparent wrong done to the Israeli soldiers themselves. Can you imagine what it would be like to have to break into some house and kill a terrified woman and her children? The brutalising effect on these Israeli soldiers is disturbing.
