2 Corinthians 10:12—For we don’t dare classify or compare ourselves with some who commend themselves. But in measuring themselves by themselves and comparing themselves to themselves, they lack understanding.
Three definitions for the word compare are worth noting. One is to appear in a similar standing, a second is to differ in quality or specified accomplishment and the third is to vie or rival. In the tenth chapter of his second letter to the Corinthians, Paul notes that the act of comparison is unwise when believers do so with other believers.
