Don't consider yourself to be wise; fear the LORD and turn away from evil.1
It is easy for an apologist to think of themselves as wise. This proverb warns to turn away from such pride and to fear the LORD who is the source of wisdom (i.e. humility). It also exhorts the importance of turning away from evil (i.e. righteousness). Both of these qualities develop an apologist of character; showing that their knowledge of the truth results in the implementation of the truth in their life.
Stand firm in Christ,
