Matt. 19:14: 'Jesus said, “Let the little children come to me, and do not hinder them, for the kingdom of heaven belongs to such as these."'

1 Cor. 2:14: "The natural man does not receive the gifts of the Spirit of God, for they are folly to him, and he is not able to understand them because they are spiritually discerned."

Heb. 1:1-3: "Now faith is the assurance of things hoped for, the conviction of things not seen. For by it the men of old received divine approval. By faith we understand that the world was created by the word of God, so that what is seen was made out of things which do not appear."

Rationality deals with what's observable or logically or empirically supportable in nature, but Christianity wants a childlike, faithful flock that focuses on a so-called spiritual world beyond nature.

And if you're free to see things differently from Christianity, that religion doesn't honour that different perspective. All non-Christian ways of understanding the world are condemned as sins or as excuses for sins.

The secular world might have been a hard sell in the illiterate fishing communities of ancient Judea or in the comparable, rural Republican regions of the United States. But the more educated zones of the free, modern world are all quite secular.
