Proverbs 20:22 God provides solutions to those who pursue His way in the midst of persecution.

Do not say, “I will recompense evil”; Wait for the Lord, and He will save you.  -Proverbs 20:22 (NKJV)

When evil people attack us, the natural reaction is to strike back.  We get angry and search for ways to retaliate.  Our solutions generally will make the matter worse.  This word of wisdom advises us to "wait on the Lord".  This does NOT mean that we do nothing.  Instead, we fight the urge to react irrationally and pursue wise council.  We refuse to speak emotionally because that makes it easier to do what is unproductive. The wisdom we need to deal with the issue is available to us. "Waiting" is not easy, but it is worthwhile.   God has promised to deliver us if we choose to "wait".
