The wise man listens to instruction and strives to base his life upon it. The wise humbly accept that they do not know all things and must be taught by God.
But fools, those who hate wisdom, prattle on and on about their own opinions. They believe anything is true simply because they think it.
It is difficult to reason with them, because although they scoff at religious truth as mere “religion,” it is really they who exhibit a far more extreme version of “blind faith” than any Christian believer who sees faith and reason as compatible.
Only a fool would say that Jesus lied about the flesh not helping at all and would insist that it does when Jesus Himself said it doesn’t.
He knows flesh doesn’t do anything and He came right out and said so.
Spiritual life is given through the Holy Spirit who regenerates the person who believes.
That’s the ONLY way for the spirit to be reborn is through spiritual means.
Physical actions and activities do NOT impart spiritual life.
