The human governments and cultures of nations aren’t sources of darkness and abuse simply because evil people are ruling in them and influencing them.
Darkness overtakes cultures and governments because sons and daughters of Yahweh are not rising up to bring influence to them from their relationships with the King of Righteousness.
You may feel as unempowered or unimpressive as Gideon, who was hiding in a winepress when the messenger of Yahweh found him and called him a “mighty warrior,” (Judges 6:11-16). You may still, however, be called to make a great difference in the earth – either by doing something to influence culture, or to influence a person who proceeds to do so.
“But I will be with you,” the Lord said to him.
