It is a myth that man in his natural state is genuinely seeking God. Men do seek God. But they do not seek him for who he is. They seek him in a pinch as one who might preserve them from death or enhance their worldly enjoyments. Apart from conversion, no one comes to the light of God.
John PiperThe missionary question is not, 'Where are there unbelievers?' and then send a missionary there. There are unbelievers everywhere! The missionary question is, 'Where are there people's who don't have any Christians in them or don't have a church strong enough to do the neighbor evangelism that we can do if we just want to do it?' That's the missionary question.
