It all depends on the premise from which you begin. I’m tired of the arguments of Christians of all stripes that
The bible is the inspired word of God
Jesus died for me
He really did rise from the dead
Jesus was, in some sense, the son of God
God, or Jesus, loves us and wants to have relationship with us
God, or Jesus, will forgive our sins if only we ask him
He has supernaturally changed the lives of millions
We are all, whether we realise it or not, involved in a spiritual battle
Jesus is coming back soon to judge the world
Most people will go to Hell, a select few to Heaven
We can argue with Christians about these claims – and others you can probably think of yourself – pointing out how the Bible really can’t self-authenticate itself, that just because it appears to say it’s the Word of God doesn’t mean it is; arguing about who wrote the gospels and whether they can be trusted; disputing the resurrection when the bible’s own accounts are so inconsistent; challenging the theology behind Paul’s redemption formula… and so on.
But really, why bother? Take a step back.
All of these ideas are dependent on one thing: that there is a God.
Yet there is no evidence there is. Christians will tell us that that the absence of evidence doesn’t necessarily equate with evidence of absence, but in this case it does. The absence of evidence that I keep a pink unicorn in my garage is fairly conclusive evidence that I don’t – and so it is with God. The evidence for him is circumstantial and so remarkably thin that the probability he exists is virtually zero (I’ve discussed this previously; here, for example). What humans have imagined him to be is not evidence of his external reality; a book written by superstitious sheep-herders and first century fanatics certainly isn’t. And beyond that? Nothing.
It follows that if God doesn’t exist then
the Bible can’t be his inspired word;
Jesus cannot be his son;
God cannot have sent Jesus to redeem us;
he cannot have raised Jesus from the dead;
he cannot be offended by ‘sin’;
it cannot be God who changes lives;
heaven and hell are not real;
the whole panoply of supernatural beings that populate the bible don’t exist either.
Take away God (and he was never there in the first place) and Christianity with its claims of the supernatural, salvation and eternal life, crumbles to nothing. It is nothing.
So it all depends on your premise. If you’re prepared to believe, against the evidence, that God exists you’ll find substance in the claims of religion. If you recognise that he doesn’t, however, you will also recognise that religion’s claims are illusory, fallacious, deceptive. No need to get involved in fruitless arguments with believers about it; that’s how it is.
