When in doubt, quote Heinlein:
“A religion is sometime a source of happiness, and I would not deprive anyone of happiness. But it is a comfort appropriate for the weak, not for the strong. The great trouble with religion — any religion — is that a religionist, having accepted certain propositions by faith, cannot thereafter judge those propositions by evidence. One may bask at the warm fire of faith or choose to live in the bleak uncertainty of reason — but one cannot have both.”
This quote is both illogical and irrationale. Of course a person can think both rationally and with faith.
Further, I’m a Christian because I have faith that Jesus Christ is the Son of Man and came to save us. However, if somebody provided me with unquestioned evidence that Jesus Christ was a fraud...my faith would cease instantly.
I think the belly of laughs is on Heinlein. He seems to reserve a low opinion of the thinking skills of people of Faith, when those opinions should be reserved for himself.
No, Heinlein had a razor sharp mind. The problem is that he had a blind spot. Paul described this in the 3rd and 4th chapters of 2 Corinthians, calling it a veil that prevented people from seeing the truth of the Gospel. Also, in 1 Corinthians 1, he wrote: "For the message of the cross is foolishness to those who are perishing, but to us who are being saved it is the power of God."
