This example of Jesus dealing individually and personally with an Iranian Muslim is quite extraordinary.
Afshin was in prison, there was nobody to tell him about Jesus, he had no access to a Bible, articles, or books that might explain what it is to be a believer. There was no-one to answer his questions or bring the truth to him.
Here, in his own words, he explains how he came to believe. Nothing can prevent Jesus reaching you and changing you, not isolation, or ignorance, or lack of resources. However, like Afshin you need to recognise that nothing you can do for yourself is sufficient, that you cannot save yourself. You cannot lift yourself into the Presence of the Almighty. But he can lift you into his own presence if you are willing to know your need of him!
