Isaiah 1:16-17

Wash yourselves, make yourselves clean; get your evil deeds out of My sight. Stop doing evil, learn to do good. Seek justice, rebuke the ruthless, defend the fatherless, plead for the (rights of the) widow (in court).

God wants us to stand up for what is right in His sight on this earth. We are to rule and reign and stand for justice against evil. That means we should stand for what is right in our homes, communities, and country. We are the light in the darkness and the standard-bearer for God on this earth.
