He claims to be a Christian and has no problem paying off someone like John that has blasphemed Jesus Christ? That says a lot about Rush's priorities and spiritual state.
Evidently you didn’t hear about Rush and John emailing each other for quite some time. It all started when Rush had his heart attack, and John happened to be staying at the same hotel. John was genuinely concerned about Rush, and asked the hotel about Rush’s condition.
Since then, Rush and John have been emailing on a regular basis.
As for being a “Christian” .. even Jesus sat down with theives to eat a meal.
Besides, I doubt you give a rip about Rush’s priorities or spiritual state.
