By an act of faith, Rahab, the Jericho harlot, welcomed the spies and escaped the destruction that came on those who refused to trust God. (The Message)

The more I see of the brokenness of the world, the more convinced I am that the Bible is correct in its diagnosis of the human condition, and in its prescription of Jesus as the only cure. Nevertheless, most people, even if they admit something is wrong, are desperate to find some other answer, to pick up a different prescription.

It is not that we can’t believe, but rather that we won’t believe. (See John 12:37, 39).

‘The prevalence of unbelief and indifference in the present day ought not to surprise us. It is just one of the evidences of that mighty foundational doctrine, the total corruption and fall of man. How feebly we grasp and realise that doctrine is proved by our surprise at human incredulity. We only half believe the heart’s deceitfulness. Let us read our Bibles more attentively and search their contents more carefully. Even when Christ wrought miracles and preached sermons, there were numbers of his hearers who remained utterly unmoved. What right have we to wonder if the hearers of modern sermons in countless sermons remain unbelieving?.. Man’s obstinate unbelief is one among many indirect proofs that the Bible is true. The clearest prophecy in Isaiah begins with the solemn question, ”Who hath believed?” (Isaiah 53:1).’ J.C. Ryle: ‘Expository Thoughts on the Gospel of John’, p.222.

As Paul infers in Romans 1, it is utterly clear from the created order that there is a God. But this is an inconvenient truth to sinful people, so we deliberately try to suppress it.
