OK, so explain exactly what you mean by “but the coup de grace has to be issued through evangelists, so to speak.” A Bible reference or two would help.
How about good ole John 3:16.
I’m not speaking of mixing the secular government and the church’s sphere, in fact if you have followed me you will see I have protested vigorously against such a mix. Church is for voluntary attendees. A country is for whoever was born there.
Get the light shining from the church, reignited with the help of evangelists who are obeying the call of God upon them, and governments will fear God and cease from the evil that plagues their spheres.
Now was that all that terrible a proposition?
Proverbs 14:34 too. Righteousness exalts a nation, but sin is a reproach to any people.
