For the wisdom of this world is foolishness with God. For it is written, He taketh the wise in their own craftiness.
1 Corinthians 3:19
It's just saying that God is smarter than us. Well yes, I would hope so! But it is often said by so-called believers in such a way as to tell others they are foolish. But really, their wisdom too is not God's wisdom. Even though some of them seem to think they're chosen by God or something ..
Chosen to argue on Internet forums? LOL. Not much of a calling really, if you ask me. Get out there are preach it to the people on the street. I'd like to see that, I can't imagine there would be much "righteous anger".
