But wisdom is shown to be right by its results. (The Bible)

The proof is in the pudding. “Generally, the expression [is] used to say that the real worth… of something can only be determined by putting it to the test by trying…it, …just as the best test of a pudding is to eat it” (dictionary). That’s certainly true about thinking matters. Talk is cheap; the test is in the reality of its expression.

If you are wise and understand God’s ways, prove it by living an honorable life, doing good works with the humility that comes from wisdom. (James 3:13)
