Cognitive dissonance....
In his mind had the rain not come, Jehovah rewarded him for being faithful in small, the rain did come just as it is written, unforssen circumstances etc. His putting his god first was tested to the full by satans world, and it cost him dearly, but he is storing up treasures in heaven.
My point is, when someone is adopting cognitive dissonance, they can easily fabricate an answer that suits their belief system. He may be smart, but he is using very different reasoning when conidering his beliefs, protecting them with his mind from all reasonable questioning and legitimate doubt.
He should have stayed home that day and deep down inside I bet he ponders why and how that could have happened when he was doing the 'right thing'...Especially every assembly when someone talks about how a cheque of the exact right amount arrived on tax rebate day or how a box of vegetables was dropt off when the bread and milk ran out when pioneering....... derp.....
