Can you give me an example? See, the problem.is that "teachings" are per se not convincing without all the supernatural stuff unless they have merit on their own. In that case though, they simply become ideas. I think I'm always open to good ideas, but what do you imply - that atheists reject ideas simply because they appear in the context of some religion? I don't think that happens a lot. Or what is it you propose? That I read all religious texts to look for input? That's incredibly inefficient, I don't have time for that! But some atheists actually do that, like meditation techniques or whatever. I'm still unsure what kind of wisdom you hope to find, though...
The fool hath said in his heart, There is a God. They are corrupt, they have done abominable works, there is none that doeth good.
Psalm 14, KJV revised edition
