Judas Iscariot reasoned that it was time to cash out on Jesus. He reasoned Jesus wasn’t going anywhere after all, and that he should make the most of three years of following the loser named Jesus.
Job’s friends reasoned against their friend. Instead of consoling him, they blamed him. You must have sinned because look at the proof: God’s not with you anymore.
The very same logical fallacies atheists accuse us of using, they too use! (When a pseudo-intellectual brandishes an exotic Latin fallacy, it tends to quiet the non-Latin speaker.)
As Christians, we too can “reason” ourselves out of the will of God. We can “reason” our way of out going to church, tithing, outreaching, our marriage, etc.
To avoid this pratfall, bathe your decisions in prayer. Make sure you don’t spend your time praying trying to convince God that He ought to approve your previously determined decision.
